Exclusion playlists

[Oldemario]

It would be great if one could create an exclusion playlist. So, one could add songs to a "exclusion playlist" and Spotify would exclude them from it's algorithms i.e. if i would like to listen a radio based on certain artist, Spotify would not suggest/include the songs on exclusion playlist. This would be good feature for finding new songs from a certain artist/genre, because the "obvious" songs would not be included in the mix.
