Eh, kind of. It’s not nearly as customizable as Slacker was. With Slacker I could say I want mostly artists I have selected, but play some new artists, and play the deep cuts instead of the popular songs. You could ban artists from a station or add ones you liked to build it out. And, I think this is most important, all your likes/dislikes/whatever only applied to the current station. I’m tired of YouTube Music playing death metal when I play Blind Guardian radio just because I also listen to death metal.
It kind of lives on in Liveone, who bought Slacker, but their whole app is a mess and they have a very limited library compared to the other streaming services.
