Hi @LoisNelson !
In the Deezer app, the "Music" section is mainly separated in two different kind of "playlists":
Made for you:
"flow": automatic playlist which is trying to mix some of your favorites with other songs it thinks you could like. It is designed as the "one easy click" way of starting to listen to something when you don't know what to listen ^^ The algorithm is mainly based on your favorites (tracks, artists, albums), or on the contrary the tracks you have marked as "not happy with", and the favorites of other people who tend to listen to the same thing as you...
"daily" mixes: a bit like the flow, but inspired by specific artists, if you want a more specific mood / ambiance. Selected artists change every day, and tend to be the one you've listened to lately.
"discovery": playlist created every week with songs Deezer thinks you don't know but you could like
and some other automatic playlists based on the current time / day, but adapted to your taste (at least the algorithm is trying to).
Other playlist recommendations like by genre, recommended playlists, selections, etc...
In sum-up:
The "made for you" section are selections automatically made to fit to your tastes, using an algorithm.
On the contrary, the other playlists are mainly manually edited and updated
There are also a lot of other cool stuff, like new releases on artists you like, podcasts or even radios.
Last advice: don't hesitate to mark a track you like as a favorite: the more you do that, the more the "flow" feature and other recommandation will be precise
