I regret very much that
is closed with no-intent-to-fix. The existing association algorithms of Spotify should be improved to better & faster learn from repeated "dislikes" on artists and genres. In my case, I already gave many "dislikes" on Drake and rap songs (no offence meant, I respect people loving this music). Or Spotify should add a feature allowing to block/unblock artists and genres. Please vote +1 on this topic if you agree that Spotify can be improved on this.
