We should rename from "Blacklist" to "Disable".

I would expect that the song remain on the playlist, but just be faded to indicate that it's disabled as proposed in #115 and the song would be skipped when the player gets to that point in the playlist. That way if a user "enables" the song later, their playlists are still intact. If they want to remove it from a playlist, they can choose the "remove from playlist" option (which still remains to be implemented).
