Let me block playlists

I've seen a number of playlists with highly offensive lyrics.  "Offensive" is a highly subjective topic that cannot be clearly defined.  If you want to happily listen to this crap, go right ahead, just don't make me.  Most of my opponents are good about this, and do their best to avoid sending these ones, but then theres others who don't care and I have to delete them, and a few that were outraged by my opinion and want to pick a chat fight.

Just give me the option to block such playlists, nobody even needs to know that I'm blocking them.
