Sounds like Spotify is going down Pandora's path then.

It's amazing how several different stations started from the same genre will narrowly converge even after explicitly disliking different subgenre-specific songs on each station. But that's been Pandora for years now; why I still revisit it time to time is beyond me.

I agree about the radio, but "similar artists" is still pretty reliable ime.

Yeah, that's the only thing that still works decently. Song radio and custom playlist radio feed you into your own preferences.
