The whole album, really
Tell me an artist you love and I’ll give you one back — off my own playlists, never one of mine, and handed over on something.
Everything comes from 3,997 songs across 32 of my own playlists, and it will never hand you one of mine. If I already have the artist you typed, you get whatever sits next to them in my library. If I don’t, it works out from the genre. The same artist always gives the same song, so you can compare with someone.
