0:00Spotify's chief product officer, chief technology officer, and co-president joins us for a deep conversation about how AI is changing the music industry, podcasts, and audiobooks from recommendations to synthetic content. That's coming up right after this.

0:20You're used to hearing my voice on the world bringing you interviews from around the globe. And you hear me reporting environment and climate news. I'm Carolyn Buehler. And I'm Marco Werman. We're now with you hosting The World Together. More global journalism with a fresh new sound. Listen to the world on your local public radio station and wherever you find your podcasts.

0:47Welcome to Big Technology Podcast, a show for cool-headed, nuanced conversation of the tech world and beyond. We have a great show for you today because we're sitting here in Four World Trade Center, Spotify's New York City headquarters with the company's co-president, chief product officer, and Chief Technology Officer. Yes, all that in one. Gustav Soderstrom is here. Gustav, great to see you. Welcome to Big Technology. Thank you for having me, Alex. It's a pleasure to be here. Very excited. Great to be here. I mean, we're in a beautiful studio in your office. I've been looking around. I just can't believe how amazing the studio is.

1:18And also, it's cool for me to be sitting here with you because I'm using your app every day. And Spotify is the place where I touch some of the most, I wouldn't even call it possessions because I'm subscribed to it but one of the most beloved experiences that i have which is music and so many of us use spotify all the time but we hear from you guys rarely so i do appreciate the opportunity to speak with you me too i try i appreciate that i'm very glad to hear that and i'd love to share as much as i can about how spotify actually works it's sort of a passion of mine to try to explain things and and how they work so i i actually love these podcasts in some ways an app will determine how people experience a format, but in some ways, a moment in time will determine how an app has to deal with the content within it.

2:05And Spotify is going through both of those. Both of those regard artificial intelligence. I don't know if you've heard of Suno. In fact, I'm sure you've heard of Suno. It's one of our favorite things to use on Big Technology Podcast. Ranjan and I, we do this show on Friday. We built a theme song with Suno and played it, and it was a good time.

2:35I'm curious from your perspective, running product, that's Spotify, how do you feel about AI music, AI generated music? Because the songs, they're not amazing, but they're good. There've been some big hits. Do you view this as an opportunity, a threat? Do you want it on your platform? So the way I think about it, I'm a technologist, so obviously I'm very excited about the technology itself. And I love AI. I think it's a super impressive product. It works amazingly well. And it's philosophically very interesting that something we thought was impossible just a few years ago, that a machine could sound like something a human did.

3:14It can be creative. Legitimately incredible. You prompt it and out comes a great sounding song. It is incredible. So I think that technology is amazing. Now, my interest is to think of these technologies as tools. So if you think about music, it's going through a journey of more capable tools. If you go way back, if you were a musical genius, like a Bach or someone, you literally needed access to an orchestra to be able to realize that genius. Even if you could play multiple instruments yourself, you couldn't play them at the same time. So you actually needed like an orchestra. and then we got to recording music and you could record one instrument at a time so you got more and more independent and then somewhere around the 80s the synthesizer came along and made that and meant that you didn't have to be able to play all the instruments yourself you could you could sort of quote unquote fake the drums using the synthesizer and the guitar and so forth so i think there's been this progression of more more powerful tools that enabled more and more creativity and And then somewhere in the 90s, the DAW, the digital audio workstation, came along and being a Swede, very proud of this, someone like Avicii came along.

4:22And what is interesting with Avicii is he was not very proficient at any one instrument or a singer. So in a previous world, he would not have been considered a very creative person because he couldn't realize that. With access to this tool, the digital audio workstation, it turns out he was one of the most creative people we had that we are very, very proud of. so so for for him the digital audio workstation was as steve jobs would say a bicycle for the mind it meant that he could he get more productive and he could he could express his genius and the big question with this next round of tools is the same is it amplifying creativity or is it replacing people and i i think it's amplifying creativity it is giving more and more people the access to be creative.

5:08You need even less motor skills on a piano or something. You need less technical skills in a digital audio workstation. So I think of them as tools. And I think there's this interesting question on what is AI music? I think people say AI music, and they mean something that was prompted with not too much of a prompt and not too much work, so like 100 % AI. But the truth is that much of music being made today is a combination. I think many of the big artists are using AI for parts of their songs, parts of the track with the drums, etc. So I think there's actually a scale between zero AI and 100 % AI.

5:46And I think we're on this this progression where it's actually going to be very difficult to say what is an AI song. Does it have to be 100, 99%, 70%, 50 %? But the real question is, do you welcome this stuff on your platform? Let's say somebody does prompt 100 % AI. Spotify could fill up with songs that are AI prompted. It's very easy to create these songs and then upload them to the internet. How do you feel about those? Do you want them? So there are two questions there. One is, what is Spotify about? We're a tool for creators. And if creators want to use AI to enhance their music, as long as we follow the legislation and copyright laws, we want them to be able to monetize their music and pay out.

6:26So for us, we are trying to support creators. And the music catalog has grown tremendously since we started, from tens of millions of tracks to hundreds of millions of tracks and i think it's going to keep expanding but what i think is important for for us to figure out that i think is our job and the rest of the music industry is if you go back to the years of piracy there was this technology called peer-to-peer and file sharing that was amazing you worked on that early on exactly that exactly we actually incorporated that technology into to spotify but before spotify the technology sort of preceded the business model.

7:03It was great for consumers. They could now get all of this music for free, but it didn't work for creators. And I think we're in the same period of time now where the technology has preceded the business model. So I think the technology is great. I do think we need to find a way for the creators who have participated in this to be reimbursed. So that's something that we are thinking about and the rest of the industry is thinking about. If we can find a business model. I think we could unlock a tremendous amount. So there's a separate question, which is then these models, the way they were trained, will that be considered legal or not?

7:41Which is a legal question that is being decided on some time period. For example, in the US, these companies are now sued. So I think that question will be decided by legislation. But let's assume that there is one of these models, whether it has to be retrained on other data or not. Is that an interesting tool for us if it was trained legally? yes if creators can participate in it so first of all it's good to hear that you're already thinking about issues of compensating creators musicians because you know i write text in addition to podcasting and i know that models have trained on my text and previously i'm not going to see a dime on that um it's a little different right with music but yeah if you can channel different musicians there should be i think some remuneration um but i'm going to just ask one last time on this point then we're going to move on um so meta for instance they have ai generators the feeds have i won't say filled but there's lots of ai generated images they're engaging meta seems to be okay with this it doesn't ban it and now some of the top content on a meta platform is shrimp jesus which sort of combines like two people's great loves which is god jesus and seafood and i've seen that yeah it's it's massive these type of images are massive on meta so from a spotify perspective if these songs generated by ai music generators become engaging and let's say they follow the rules is that good for spotify well i think like this if creators are using this uh these technologies they are creating music in a legal way that we reimburse and people listen to them and they are successful we should let people listen to them i think what is different though i don't think it's our job to generate that music instead of the creators right that's a that's a key difference are we as a platform for creators and then we can have a discussion on which tools are they allowed to use like they could use the other workstation but not lm maybe that's not actually we should we shouldn't decide that for them but there is a question should we generate all the music ourselves and that's where we're saying no we're not going to generate that music and other platforms maybe will because it's cheap content, right?

9:49So that's the key difference of we decided what we want to be in this world and it's a platform for creators. Then there's a question of which tools they are allowed to have, which is partially a legal question and partially up to the creators, I think. Okay. So there's a potential world where one of these tools seems to have violated copyright and you might ban creators from uploading music that have used that tool. we're already taking if we get we have detection systems for if you if you are um if it's a derivative work of of something that already exists so we have systems to take these down uh if you're creating something completely new that isn't a derivative of anything there isn't that there isn't a copyright infringement then the labels tell us so so that's the other question on like what are these models trained on and we're not creating this model so so we're watching what happens there and we're going to follow the law but i think from a high level this should be a very exciting tool for creators for for musicians for authors for podcasters i i think i think if you look at something like notebook lm for example it's actually created by a journalist and a writer as a tool so i i think my bet is that these are bicycles for the mind but sort of bicycles for the mind on steroids right and that when those shifts happens there is always tension between the the people who didn't use these tools it feels like this is a little bit like cheating and the people are saying like, no, I want to be creative too.

11:14And it's always a different, difficult transition period. It's just the story of technology. And by the way, we're going to get to Notebook LM in a bit. So I definitely want to hear your perspective on that. But let me ask this one. So first of all, what you're describing is just sort of like, this is what happens in tech companies. You think you have something figured out. And then next thing you know, new innovation, you have to account for it. It's kind of what makes it exciting. It's what makes it fun. That it happens. And you already have addressed where this is going, which is, do we get to a place where, remember, you started talking about this saying we never could have anticipated that this is possible.

11:51And now it's like, feels like magic prompt and you get a song out. And I called them great earlier. They're not great, but they're good enough. And this is literally first generation of this stuff. It's going to get better. and as you think deeper about it do we go to a place where you can start to prompt music that is going to be better than any song that you might listen to that has been created for certain moods for instance like let's say you're in like a introspective mood or in a loving mood or in an angry mood and you're just able to prompt it and create that song that perfectly touches the heart at that moment and i started off talking about how this this format is beloved music is beloved it touches the heart and if ai can do that does that become the future of music so you've already said you don't want to play in it but is that something that you can discount from coming in so i think two things um music is used for many different things right um and so you have for example music that you're using to study i think is a good example the extreme version of that is people listen to white noise.

12:59So like, would white noise be generated? It's actually already artificially generated. It's one of the top podcast formats on Spotify. Exactly, right. So there's a scale here. And I think you're right. For certain things, maybe you could create better white noise. Maybe you could create better, you know, always varying ambient music for your studying. Maybe for gaming, maybe that music should automatically adjust to what's happening on the screen. So I think we're going to see lots of AI generated music for those use cases. but there's another use case for that which i think is very important a lot of people use music to build their identity right especially when you're a teenager you go to a concert you buy the jacket from that concert why did why did you buy that jacket well it's it's a it's a it's like a pin you're identifying with this band you're building your own identity through this band i don't think that will work with ai generated music because there is no one behind it so i I think some music, and I'm sure this is happening already.

13:54I'm sure many publishers are generating music for coffee tables and so forth. That will probably happen. But I do think the human need for having someone to believe in, an actual artist that you care about, I don't think Taylor Swift will be replaced by an AI. Not because the music couldn't sound similar, but because the whole point is Taylor Swift and belonging to something. So I think it's not a binary answer. Is this going to happen or not? know it's gonna not gonna happen i think both both will probably happen you know two years ago i might have fully agreed with you that there's always going to be that need for the story and the human connection and now i'm not so sure because because i do think that that this stuff can be good enough it's already proven that it's it it's already exceeded some of our greatest expectations and um i think we would like to think that we want that connection with the human but all right let's go right into notebook lm but but i think yeah one thing to say that i think is interesting is what tends to happen in these worlds is that the thing that is scarce gets even more valuable so one bet would be that true human connection gets more valuable than ever when a lot of what you talk to in the future may be llms that that would be my bet i'm hoping that's the case because part of the business that I'm running is predicated on the idea of connecting to a human who can sort of dissect and break stuff down is valuable.

15:22So I'm hoping that is the case. But I also, I'm not as sure as I used to be. And I think it's wise to not be sure of anything right now, given the pace of progress. And I think that brings us right into Notebook LM, which I was planning to leave for later, but you set it up perfectly. And it's this Google product that you can put notes in and then it will actually generate this podcast uh with two co-hosts that sound like ridiculously human yeah they don't they don't sound like robots and in fact people have sort of like uh fed them scripts where they like realize that they're actually not real people and they're ais and they just have this kind of breakdown and it's insanely entertaining but the bottom line is they're not quite where they need to be they're still a little hokey I think, and just kind of, they're like, if you listen for a minute, you're blown away.

16:12If you listen for five minutes, you start to cringe. But they also do a good enough job of breaking things down where they can pass. And I started to see them right now showing up in the second half of episodes where people are like, we're going to do the episode. And in the second half, we're going to give you the AI to listen to. But what happens if they end up being the first half? And Spotify has made a big move into podcasts. What do you think about the rise of these AI podcast hosts? So I think Notebook LM is very impressive. And you could predict, given the evolution of voice quality of these things and understanding of a language model, that this would happen.

16:51So I'm not at all surprised in a sense that you can generate audio that is engaging to listen to talk audio. But what I think was the great innovation of Notebook LM was that people generated monologues. And what humans really respond to are dialogues. And in retrospect, it's pretty obvious, like almost all podcasts are dialogues. Like if I sat here for one hour, it's not that interesting. So I think the big hack was to go through a piece of material and present it as a dialogue and prompt it the right way. There was also obviously, you know, the internal Gemini model at Google that is probably very good.

17:26and the voice models got better but i actually think what they found was product market fit for the actual audio format and it turned out to be the podcast format quite quite literally it's pretty crazy i mean somebody on threads tagged me and was like the male voice sounds like you and i listened and i was like not the same tone but also the cadence and the type of questions i'm like does that mean that i'm just like the blend of of all different i like this like you know kind of um the unremarkable middle of this? Or do they copy my voice? I'm hoping it's the second one. It'll be interesting to see if people either get tired of hearing the same two people talk about everything or the opposite.

18:05They get used to the same two people and would prefer to hear the same two people and build trust. I don't know. I think humans are very quick and prone to sort of anthropomorphize and it's sort of a hack on our human brain. So you feel like you know these people because you heard them talk about so many things now. so I think it's very interesting it's hard to predict where we'll go as a platform we view it the same way of course people are uploading these podcasts to Spotify as well and I don't know from the top of my head how you know if anyone has super high engagement but certainly people are are listening to them so it's the same question does this turn into a tool for creative people who can write stories but don't want to have the podcast around it or or just have no one interviewing them so they just do an interview around their own material I don't think I think you're going to run into the same problem where if you just ask it to talk about something it's not going to be very good you need a good source material so it's the same question is this a tool for creative people to get even more productive and creative or is it replacement of creative people my bet is it's another tool it's pretty interesting because it sort of broadens out the long tail and for those not familiar with the industry jargon it's basically just that like a lot of listening is concentrated in a small amount of shows yeah and there's this great long tail right like if you think about like a bar chart as it just sweeps out and there's uh lots of you know seldomly listened to shows yeah and the thing about these podcast generators notebook lm in particular is you can take it and create a podcast for something that's so niche that you would never have a show similar with ai code right you can start coding things i think you spoke about this in your interview with tomah cohn yeah uh on building one another linkedin podcast network show where now you'll code things that you would never code before because you can do it and it's similar it might go the same way with podcasts where you can for instance when i before i was uh heading down to manlo park to interview andrew bosworth i just dumped in all my source material and it read me a created a podcast about like his current statements there was like seven interviews that him and Zuck did before I showed up there and I was able to get the summary.

20:20That podcast never would have actually made sense to produce. But for me, it made sense. And maybe that's where this goes. Yeah, I love that framing. Like one useful framing, I think, of these techniques is financial framing. Like the cost of something goes to zero, like the cost of writing code goes to zero. Cost of doing a podcast goes to zero. Cost of prediction goes to zero. What happens? You know, and usually what happens is is the the alternatives to that good. they get challenged but the compliments to that good you know you have the famous like what if the the the uh price of coffee goes to zero then then the tea is going to be replaced but sugar is a compliment is going to explode so i like that way of of thinking about it and and i think what's going to happen is exactly what you're saying we're going to have enormous amounts of content around niches where it didn't make sense to produce a podcast so one way to think about it is just like the cost went to zero so i do think that the catalog is going to explode and then what does that mean well it probably means that the recommendation problem becomes even more important because now it's even harder to keep track of everything that is uploaded i also think that if you have this like vast sea of the perfect sort of discussion around any topic uh so the recommendation problem becomes more valuable to solve the bigger the the catalog is but i also think you're going to see the same thing as we see in music the superstars will actually also get bigger this is what i find fascinating people say like are you know netflix winning or youtube well the truth is both the tail is getting bigger but the shows are getting bigger and they're saying saying are they in this winning or taylor swift well both in this are winning but taylor swift is bigger than ever i tend to see like these both things happening at the same time which is why i'm hesitant to like say like that is going to happen right but not this yep okay let's talk about AI recommendation.

22:10It's a big part of Spotify and we're going to just start at the end for this conversation because your vision eventually is, so right now, like we'll go into Spotify, there'll be some algorithmic recommendation. There'll be some stuff that we listen to. Your vision, if I have it right, is eventually you want Spotify to be sort of this ambient friend for us that knows this context of the situations we're in, maybe AR. We're just talking about orion glasses before we start uh recording but maybe they know the context of where we are and can chime in and give us you know an example of type of some music that we might want to listen to is that right why would we why would uh why would you be pursuing that well i i do think of so when we um started spotify i was not part of funding spotify joined in 2008 late 2008 2009 Spotify was found in 2006.

23:00It was pretty early on. And it's interesting that this was before machine learning became a thing. And so Spotify was quite focused on social features for purposes of recommendation. We needed social features because that's how most people discover music, through a friend. So we wanted to connect to people. And then AI came along, or what was called machine learning back then. And we realized that through all the playlisting data we had, which is basically when we think about the playlisting data is almost as labeling for the user they are creating a set for themselves for spotify they were saying like these tracks go well together these tracks go well together so we got a lot of label data basically and we said internally now some people have a musical friend that happens to know their taste and so forth but most people don't so now we can build this friend for for everyone that was the ai but the interesting thing is like that thing of like building a friend for everyone that can give music recommendations like discover weekly it was always an analogy people did not think of discover weekly as a thought of as a set as a service and so forth i think what's happening now with ai is that the analogy is actually becoming reality and so you can see you can see us moving a little bit in that direction you have the ai dj that starts to give spotify voice that talks to you um and i think what is going to happen with these llms is at least for some brands you will start having literal relationships with them and i would love if it is the case that you think of spotify as actually a friend not an analogy anymore but reality this is a person that this is a thing that knows me well this is a musical intelligence a podcast intelligence a book intelligence and actually like hearing it you know tell me about new things and suggest things i'm interested in so i think that's that is where we're moving i think other brands are moving there as well i think if you if you look at some someone like uh duolingo they've actually only communicated through four characters all along when you get a push note if it's not from duolingo it's from lily or star or something they really they uh they give me a hard time if i'm away for a couple hours and that was also kind of an analogy but now with ai you can actually talk to these characters so I think this is a journey many companies are on.

25:14And it's interesting to play that out. It means that part of what was called branding before is like, what personality do you want your company to have? Not as an analogy, but literally. What personality should Spotify have? I think that's a fascinating time to work in tech. And it's something we're thinking a lot about. And I think that you might be underrating how much people view Discover Weekly as a friend. Now for folks who don't use Spotify, Discover Weekly will basically take into account your listening and your preferences and give you a playlist of what, 30 songs on a Monday morning. And they're just new songs for you to discover.

25:47And people will be like, Discover Weekly really got me this week or Discover Weekly is inflecting some pain on me this week or what happened. I thought we had a close relationship and now you don't owe me at all. And you also have, so you have this AI DJ. You can find it in the app. It's okay. I think there's definite, I'm curious, the feedback I've heard is people were excited about it initially and have moved away from it. And what is, so now I'm sitting in front of the person running product at Spotify. What is actually happening with this AI DJ? Is the experience there and are people using it?

26:23Yeah. So in the numbers, they're not moving away from it. It's actually very successful. So my friends are just pretty snobby music listeners. Well, for the people that use it, it's actually their biggest set. It's bigger than their Discover Weekly usage. So it's quite a binary experience. I think it's for people who don't know what they want to listen to and just want to put something on. It's working very, very well. What I would say, though, is when we launched the AI DJ, the big innovation there was that we managed to basically digitize the voice of a real person to make it sound very believable.

26:57But the things that it said around the music were, like, to some extent, heuristics and kind of repetitive after a while. So what we've done since then is we've invested quite a lot in, this is quite recent that is rolling out, in LLMs that actually tell interesting stories about the music. And we see very strong effects on this, on the retention of the application. So whereas the thing used to say, here's this and this song from this and that, I think you'll like it. Now I can say things like, this artist was just in Copenhagen or has played here and here the last week. Okay, I have to re-engage.

27:30You're starting to get interesting stories. You're starting to feel more personal. the other thing that i think is missing that i hope we can do someday is it can talk to you and you can talk back by skipping but obviously in the in the age of like talking to machines you would like to be able to just talk to it and say like no this was not very good my discover weekly this week was not what i wanted and give actual feedback and that is technically very possible now with these llms so so that's what i'm hoping will happen this should not be a one-way relationship which Spotify has been for technical reasons, it should turn into a two-way relationship.

28:06Okay. I have questions about that coming up. And to introduce that segment, I want to talk to you a little bit about how much we should allow the algorithms to dictate what our music experience and podcast experience is going to be versus how much should be dictated by us. How much agency should we have of our own choices? is Kyle Chica, New Yorker reporter, recently wrote about how he's leaving Spotify. I'm just going to put the argument out there and hear what you think. And I'll just read it straight from the story. He goes, through Spotify, I can browse many decades of published music more or less instantly.

28:44I can freely sample the work of new musicians. It has become aggravatingly difficult to find what I want to listen to. With a recent product update, he says, it became clearer than ever. what the app has been pushing me to do, listen to what it suggests, not choose my music on my own. What do you think about that argument? Well, I think this is an individual feedback, but I think generally you have very different types of users. So I'm going to get this person back on Spotify 100%. I think there's an interesting trade-off here that is real. So people want less friction. They want to spend less time searching.

29:25You want to make things as easy as possible, right? But there is this end of the line where you sit there and you just receive. You're kind of force fed and you don't give any signal back. Maybe a few clicks and so forth. And that's something that we want to avoid. I think this is where the industry is going. It's going more towards distraction content and sort of just sitting and receiving. And it's a little bit of a dystopian end of the line there. So what is interesting with Spotify, which we are reemphasizing, is that it was actually a platform where you invested quite a lot in your own playlisting, right?

29:59And there's a trade-off here between you could have a vision is we should be so good at machine learning that you should never playlist again. That would be the goal. Because then you've done the user a great service, supposedly. But then you also receive no signal and the user does no investment. So we're actually re-emphasizing playlisting quite a lot. Okay. Your own investment. And over the years, we've gone more towards machine learning and algorithms because it works. People listen more and they appreciate the service more. But we need to cater to everyone, including this reporter. So the Spotify user base is divided into many different kinds of people.

30:38You have the track listeners only listen to playlists. You have the hardcore album listeners. It's like, I just want to listen to an album the way the creator thought about it. I don't want to have the songs in between. um you have like the artists radio listeners only listen to to one one type of artist and it's a it's actually a big challenge to build a service that serves everyone when people are very different so we we try our best to make sure that the sort of music aficionados who want their library to be album album album can have their service and then but then you have the other people who just want like i just want my daily mix to play in my air i don't you know i just want to collect tracks they also need to be successful so we're trying to build and cater for both you can never please everyone 100 but we're trying to be statistical about it to make sure that it is uh it is uh vastly better for the majority of people but our goal is to cater to everyone and i do think there's a real point around going to zero user investment seems good in the short term but i don't think it's good in the long term because you actually lose signal from that user and at the end i think they feel less participatory in the experience even if the engagement looks high if you've done no feedback i don't know how much you feel this is actually your service definitely and look i'll confirm that spotify does listen to user feedback i sent a tweet out uh a couple years ago talking about how sometimes I'm baffled by the Spotify product decisions.

32:11And maybe it was because I was a reporter, but someone from your team reached out and I talked about how I wanted to see recently played. Oftentimes I'll be listening to something and then I'll go away from it and I can't find it in the app. And then a couple months later, there's a recently played button in the app. There are some great updates coming for you as well on that topic because this is a big user need. Maybe it takes a little bit longer than we want, but obviously our goal is to is to listen to user feedback and try to but we get very sometimes really completely opposing user feedback that's the tricky thing who do you listen to the most people who want this desperately or hate this desperately and there's a lot of both types of feedback so it's product development at this scale is sort of a statistical experience but you still have to have a bit of an opinion if you only treat us statistics the application is going to be very weird at the end of the day.

33:02So you have to combine some sort of vision and conviction, but you have to be still very data-driven. I think an interesting example of user investment and AI that we launched recently is something called AI Playlisting. So this is, I think, a good example of the first time you can talk to Spotify. So the AI DJ talks to you and it's getting better, but it doesn't listen. It listens to clicks maybe. But with AI playlisting, we built this experience where you can prompt what is an LLM with what kind of playlist. So we have an LLM and the LLMs have a set of world knowledge about music but then we have the music catalog and we have your listening history.

33:42So this is an LLM that understands your particular taste and you can ask it for a playlist with big drops and EDM for driving fast at night or something. And then it will try to do that And then you can say like, no, a bit more upbeat or not that artist and so forth. And this, I think, is a good mix of using AI, but not to force feed you stuff. It's actually very high signal. You are literally telling us what you want. And then when we say, here it is, you say that one, yes, no, no, yes. And then you can reprompt. So it's back to, I think it should be a two way conversation. And I think the first wave of machine learning allowed us to do the one way push.

34:22the next wave generative allows us to actually listen to you even in clear text so communicating with spotify just through skip buttons it's a pretty narrow signal so it's kind of hard for us to understand like when you skip it was it because you hated it or because you liked it but it was too many times now you can actually say like i really don't like this because like remove it so i was dming with kyle last night as like hey i'm gonna meet with gustav what should i ask him and one of the things he said is uh should spotify users be able to tweak the recommendation and your answer here is resounding yes.

Read the full transcript

34:53Absolutely, absolutely. We are working on these things, both the obvious things where you can say like, I didn't like this particular thing, but I think the free text element is very interesting. If you could talk to it, it would learn much more, but you would probably also get more trust. Definitely. Let me ask you one broader question about this because I won't stick on Kyle's stuff for the entire conversation, but I thought it was really interesting. Yeah, for sure. And he wrote a book called Filter World. The main argument, he's been on the show. I'll link it in the show notes. The main argument is that our world mediated by algorithms has become too bland.

35:30And, you know, effectively that algorithm have flattened out, you know, what used to be a more vibrant experience with things like music. Do you see that at all? I think this is a really interesting argument. There are two ways I want to address that. one is for Spotify specifically we've seen the feedback that people feel like it's great for the kind of stuff I already listen to but I feel like I'm in a bubble I'm getting more of the same I'm not getting new stuff this is sort of a Spotify specific challenge because most of the time your phone is in the pocket and you're listening and when you're listening you're listening to a session let's say you're listening to indie folk or something then it's quite easy for us to say here's another indie folk song and you're going to say oh that's a good recommendation but if we start playing metallica there you're going to be like what is this so most of the recommendation sort of inventory we have is kind of constrained naturally to what are they listening to because we can't put in very random things you would say this is a bad recommendation so this is a challenge for us when you know when we want to show you something completely new the favorite example is i love reggaeton but you wouldn't have seen that from my listening history how do we solve that problem so we started investing about two years ago in in other types of foreground recommendation so sort of like the feeds that you see on social media but you can it you can literally say like okay i'm bored i want to go wide then you can go into these um foreground feeds of music where you can swipe through many tracks and they're very efficient the hit rate is going to be low because now we're in a territory where the whole point is we don't that you like this or hit rate is going to be low then i think you need a very efficient ui to evaluate lots of content right because the hit rate may be one in 20.

37:16you're not going to listen to 20 songs there's over an hour of music you need to go quick so we try to solve that problem for for when like alex is bored and he wants to branch out as soon as we see that signal we didn't have tools for that before so so we built that so that's part of the answer spotify being an audio service made it a bit harder to go explore so now we have these foreground feeds we have music videos not in the us yet but but in much of the rest of the world we have music videos they're very helpful when you're evaluating new music but the more philosophical part of this answer is did the algorithms sort of flatten out because they are to some extent trying to find statistical patterns and averages and i think if you look at recommendation technology i don't think this is widely known yet but these deep learning based systems they had flattened out in terms of if you added more user data or more parameters, they did not get better like the other lamps.

38:08There were no scaling laws. It's just like it is what it is. And you could move at 0.2%. There's something that has happened there recently, which is called generative recommendations, where you actually use a sort of large language model instead of these old deep learning models. And you basically think of user actions as a language. So you have a sequence for you. So they click this, they listen to that, they click this, they listen to that. And then just if you turn that into tokens, just as you can turn a language into tokens, you can just as you can try to predict the missing word in a sentence, you can try to predict the missing action in a sequence.

38:45And it turns out that these generative recommendations, they do scale with more user data and more parameters, just like the LLMs. So this is a long winded way of saying, I think he's right that the recommendations did flatten out. It's also true that people are changing recommendation stacks and it now is unclear why they couldn't continuously get better so i'm hoping that the recommendations do get more intelligence because intelligent because now it's not just a statistical average they can look at your specific user history going years back and they could potentially understand that it's actually uh you know christmas again and last year at christmas you did this i'm hoping it gets more intelligent and one last question about recommendations or maybe i have two but one important one that comes from ronjan roy who's on the friday show with us he would like there to be a parent mode on spotify where if you have kids you can be like i'm on child mode and then recommend kid music and then parent mode you know and don't uh blur my recommendations what do you think about that so so we have a a bunch of different solutions for this obviously there's a family plan so hopefully your kid can have their own account and then it doesn't cost more the recommendation exactly what are you gonna do for your three-year-old exactly there's the other thing is you can create a playlist for your kid and then if you click the settings you can say do not include in my recommendations and then it actually doesn't destroy your recommendations at all so so there are those solutions we're also trying to understand that all of this is kids music so while this is part your taste profile we should not play this in your other sets because this is probably something you're doing for sort of a use case so you probably want a kids music playlist in there but you don't want that music to affect your your other sets there's an algorithmic component there's a there's a subscription plan component and then it's back to like more user control you can actually already say that this playlist should not be considered my taste and so we're going to build more of those controls okay rajan will be happy to hear that yeah uh okay really last question about recommendations then we're going to go into podcasts and some other formats um i don't know if you have seen this youtuber his name is fontana he did this thing about the shabuzi being song being the song of the summer explaining why and he made an observation there that was interesting to me talking about how we used to hear music on the radio often and that was the music that was played there was music that would often be played when we're with other people with friends having a good time and it led to more you know dance songs rock out anthems and stuff like this and today we're like mostly accessing music via streaming platforms and he says those are much more individualized recommendations which has kind of shifted the way that music is made and even the hits in music what do you think about that argument so there is a philosophical question there which has been researched a few times which is do you have an innate taste in your brain and our job is to search for that and find it or do what we play actually affect what you like and there are all these experiments in colleges where you know you play like different songs to different groups and then you see what they like and it seems like it's a bit a bit of both you have some sort of innate taste but you're also affected by what you hear to this argument like the the radio can change your your taste so so i think there's a there's two to that argument what i think is interesting about um our music listening is that when we survey users and we ask them what percentage of your listening is with others it's a huge percentage double digit percentage so music is actually a very social activity still and in some cases we see this we have this feature called jam that is taking off like a rocket for us it's doing very well and jam is essentially we can detect when two phones are close to each other it's just like hey do you want to join alex's jam and now we have a joint queue so at a party the way you party right now with spotify is you don't go and like interrupt you just bring up your phone you join the queue and then you can queue things up right and so now we have a lot of of joint listening and people are listening like i said i don't want to say the exact percentage but it's double digit percentage of listening happening in groups it just looks to individual as the individual listening to us so i think it's actually happening more than maybe people think it's not 100 individual listening but because we don't see them as group listenings we're still treating them as individual listen so now that we're getting more data on what is good group music that becomes a different category so i i think the radio use case is happening you're hearing songs at parties and with others and when you're riding in the car and so forth it just looks to these services as lonely listening but it's actually quite social right okay let's take a quick break and come back to talk about podcast audiobooks and see how many random questions i can get to before our time is out we'll be back right after this did you know your credit card points and miles can

45:20and wherever you find your podcasts.

45:29We're back here on Big Technology Podcast with Gustav Soderstrom. He's the chief product officer, chief technology officer, and co-president of Spotify. So Spotify is investing heavily in podcasts. This has been going on for a long time, first through largely through an original strategy and now less so um also audiobooks you can find my book always day one on spotify if you're a premium listener which i'm happy about because so people can listen to to the book what has gone into the decision to just bring all these formats together in one app and uh i mean are they good businesses for you spot uh podcasts and audiobooks Yes, if we start with the first one, how do we come to this decision?

46:16What happened is that we saw internally actually at Spotify, a lot of our developers sort of hacking Spotify into or hacking podcasts using RSS into the Spotify experience. And we saw it again and again at Hack Weeks. And first we thought like maybe it's a niche random need. We saw it again and again. And so then we just, it's like user feedback, user research. which Spotify is still like many thousands of employees. So it's not a very representative sample of society, but it is some sample of society. So if you see the same user need many times, you should take it seriously. So we started looking at that.

46:51And then we looked at podcasts that we saw had a lot of potential and was growing, but we didn't think anyone was doing something very interesting with it. So we decided to then just approach it because we saw the user need internally. We saw the market growing, we sized it, and then we saw that there was no one really investing in it. Apple hadn't invested in it and they had like 98 % of the market. So that's how we came to it. And then the question is... That Apple podcast app needs work. Okay, but sorry, go ahead. But we were grateful for that. So then the question is why in the same application?

47:25Why not as a separate application? And there are two views of that. One is it's a strategic decision. the biggest barrier to something new right now, unfortunately, isn't necessarily the quality of the application. It's the user acquisition cost. Distribution is everything. Distribution is still everything. And actually, at the beginning of the iPhone era, there was a lot of organic distribution. People went to the app store every day. It's like no one goes there anymore. So you almost have to pay for every new user. So user acquisition cost is probably the biggest inhibitor to most business plans.

48:00So if we built a separate app, we would have to reacquire our own users again, and that would make it very expensive. And we have seen all of these big, big companies, the American tech companies, launching app after app, and basically nothing worked. Then we look at China, which is a different strategy of the super apps, where they double down on their own distribution. And so you can think of like podcast pre-installed. So that was the strategic angle for why this made sense. But I actually have a user angle on this, where I think it is the better experience. so I think in 2024 the users should not adapt the software to the content I think in 2024 the software should adapt to the content so if you play a piece of music there should be skip buttons if you play a podcast it's not rocket science to change the skip buttons to 15 seconds scrub and if you play an audiobook to change them to chapters like come on it's 2024 why do you have to switch apps for that right right so we we actually both believe that it was strategically the best for us because then we could double down on distribution.

49:02But we also think this long term is the right user experience. It is the easiest for the user. Now we have these beautiful connections between the audiobook and the author being interviewed in a podcast on the same thing, where it's seamless instead of like, now you should switch the app and go somewhere else. So that's the reason that we do it in the same application. And talk a little bit about discoverability because that's the biggest issue for podcasts. I mean, if I, and as a company that's an expert in recommendations, which we've spent like most of this show talking about, that should be something that you get done pretty well.

49:34But for instance, like if I'm listening to tech shows and I'm not listening to big technology podcasts, I probably want to see that there's a show called big technology podcast out there. And from what I've heard, discoverability, like both from product people and from podcast producers has been the biggest issue uh probably because there's like a huge investment that goes into listening to even that first five minutes of a show i mean that's like two minutes longer than your average song to try out a new show and most of them most i mean i actually changed my show that we could do our like really like you know information rich uh intro which you just experienced and then take a break take a break and come back in because if people are going to try it out i want them to know what they're getting versus like the typical long-winded well here we are today and yeah it's beautiful so i'm just curious what you think about this discoverability thing so i think you're completely right short form formats are easier because the discovery is the consumption so like a talk on tiktok it's not like there's a recommendation for the for this talk like when you watch that you consume that music is almost the same it's three minutes it's not quite like But it's almost like if you discover it, you also consume that.

50:46Podcasts are different. You kind of need a trailer because it could be an hour of investment. Books are actually even harder. It could be 15 hours of investment. So I think a lot of the challenge is to create a good representation, a good short-form representation, this long-form content to understand if you should invest your time. And so this is something that we are investing quite a lot. The podcast world didn't have that for the longest time, right? And I think this is also part of the reason why, if you look at the old sort of Apple podcast world, it's a few shows that have a lot of followers sort of forever.

51:22But it's really hard to break in for a new show. I think this is changing now with these short-form previews that are happening on TikTok, on YouTube, on Spotify, where you can quickly go through and understand what a show is about. I think video is actually helping. It's the same in music. We see that music video is very important in the discovery moment. And actually, a new release with a music video in an A-B test does much better than a new release without a music video in terms of downstream. And I think it's the same for podcasts. If you're quickly saying, like, I'm interested in technology podcast, it's quite hard to...

51:58It helps a lot to have video for those podcasts. podcast and so this is why we built these foreground feeds where you can go through a lot of a lot of material within your interest with lower friction so we're investing quite a lot in sort of the quote-unquote preview problem and it's the same for books to get a good recommend good understanding of a book quick is hard you can use a lens for that to try to summarize them you can use the author's own summary so this is something we're investing quite a lot okay so you have been introducing video in uh for podcasts i know this one is going to be on video i'm hoping to do a lot more video podcasts through spotify uh are you going to do short form video feed tick tock like well we we already have that for the intro so as a creator you can upload your video podcast you can also choose this is the rep the short form representation i want in sort of discover feeds right so spotify has discover feeds for for music for podcasts and for books so but it's important to know they look like tick tock but on tick tock or or instagram the the item is the consumption itself right and they are measuring it on how long you stay in the feed we are actually doing something it looks the same but we're doing the complete opposite how long you how often you leave the feed how often you save it so we're trying to get saved for later so we're ranking them on how many things you save not how long you stay which drives a very different recommendation right so trying to get people to save your episode into the library to listen to the full thing so that's the optimization we actually don't want to stay in that feed we want you to quickly get through save a bunch of stuff so your library is full of interesting podcasts okay we have a couple minutes left i don't want to leave without asking this question and this will be the last one i have although sometimes i say that and end up asking a few more but let me just ask you this one and hopefully uh we'll be able to get out of here after this one uh tick tock it's such a culture setter and there are moments i think where tick where dances and songs will go viral on tick tock and quickly become the number one song in the world so just talk a little bit before we leave about the influence of tick tock on driving culture driving listening on spotify how how what's the magnitude of it what do you see on your end i mean tick tock is is huge and and instagram reels is huge like a lot of culture happens on these platforms so we've chosen as strategy to invest in these in these platforms on tick tock actually you can now save the track straight to spotify so for us this is a huge discovery funnel we also have editorial playlist called like tick tock viral hits and so forth to try to capture what is happening on those on those platforms so one way to think about it is for us this is like a top of funnel things happen there If we're well integrated, we capture the downstream listening from that.

54:45So we're trying to integrate into all of the big social platforms because a lot of culture happens there. But we also want culture to be able to happen on Spotify. So this is why we have our own editorial playlist, specifically in music. We do drive a lot of music culture. So both when it comes to being able to save from these platforms, but also being able to share to these platforms and be able to talk about spotify music on this platforms we've invested a huge amount of engineering and being making sure it's very easy to message a spotify link in a whatsapp or or or in a messenger or in something like this we want all the conversations about music to be spotify links going back and forth yeah it's fascinating it can be a little disconcerting sometimes to hear like a full version of a song that you've heard on tic tac a bunch like that apple song i didn't realize there was a beginning or an end to it i just thought it was that apple dance part of it but anyway that's true it says a lot about me i guess um so we're here at the end of of the show how often do people get to the end of podcasts on spotify they do get i would i have a number i don't know if i can share it but you know you can see a curve like this starts at 100 yeah it goes down it depends between creators but you have full of in the beginning but then after a certain point most people just go stick to the end right then there's like a really big drop drop of at like you know 90 something percent i got it usually and music or something and that does the end music hurt with discoverability because is spotify saying okay only you know we had 60 something percent up until like minute the last minute but then they go down to 30 before they complete no so we shouldn't end abruptly or should we no we control for that so we understand that this is the end credits and people move on to the so just sort of we can take our time coming in for a smooth yeah you can have but you're going to have a good exit song.

56:34It's fine. Not that many people will listen through. I can tell you that. Yes. But it's not going to hurt your recommendation score. Well, for those who've listened up until this point, we thank you for sticking through it. Gustav, great to see you. Great to speak with you. Thank you for answering all these questions. Such a pleasure being on the podcast. Really appreciate it. Great having you. All right, let's hit that exit music. Everybody, thank you so much for listening to this episode of Big Technology Podcast. Great being here at 4Weltrade Spotify headquarters and getting a chance to speak with Gustav.

57:00We're coming in for a nice, slow and lovely landing as you get on the rest of your day. And I'll see you next time on Big Technology Podcast.
