Users need different things at different lifecycle stages

Give more flexibility when a user is starting their streak. Eventually, once people get on long streaks, you don't want to give them as much flexibility.

Home refers to Spotify's main feed feature. Recall shows familiar content while discovery shows new recommendations to users.

When we tested some of them on Home, we switched it from 90/10 to 10/90. So 10% recall, 90% discovery. And while people want discovery, they probably don't want 90% discovery, instead of 90% recall.

What we hear from users again and again, though, is that they say that they get trapped in a taste bubble. So I love my Spotify, I love this, but I'm a little bit bored with EDM now and Spotify's not suggesting something completely new. And if you think about that problem, it may sound similar to the recommendation problem, it's just another recommendation problem, but it's actually fundamentally different because when you're recommending another EDM track inside the EDM playlist, you have a lot of signal from that user that they like EDM. But if you're going to recommend a completely new genre, by definition, you have no idea.
