The Star feature should be complemented with a way to mark tracks as excluded. Those tracks would then be skipped even when included in the current playlist.
This way the enjoyment of a good album wouldn't be disrupted by tracks you don't like, while the album in its entirety can still be kept in the playlist.
The Anti-star can easily be implemented as a flipside to the regular star as they are mutually exclusive. Click the star once, the track becomes a favorite. Click again, the star icon changes to the anti-star and click a third time and either flag is gone.
A no-brainer to me.

Thanks to everyone for their contribution to this thread. We really appreciate it. In the interest of full disclosure, we’d like to share with you the status of this request.
After serious consideration, we’ve decided not to offer blocking/ hiding/ or blacklisting artists or tracks on Spotify at this time. Rest assured we’re working hard to improve suggested content, such as your Discover Weekly and Release Radar. Keep an eye on the idea “Add like or dislike button to personal discover weekly playlist” for more details around this.
