I got hacked and I think I got rid of the hacker but now I have all these suggestions for hardcore gangster rap that I don’t want in my Spotify. How do I get rid of these suggested artists and playlists?
If you're seeing artists or songs that are not to your liking within the Spotify generated playlists (Discover Weekly, Release Radar, etc.) thumbs down the songs/artists you don't wish to hear anymore. And thumbs up the artists you like. This will help the Spotify recomendation engine better fit your listening habits vs. the hackers.
If you have playlists that the hacker created, delete them.
Also as said earlier. Just keep listening to music you like. This helps the algorithms fit your musical tastes.
Note: If you haven't already, change your password.
