Haha I once had the great idea to play that for my mother and she has never let me live it down.Captain Marvelous said:A little warning for this song. It does involve violence, murder, suicide, and rape. If you dislike the mention of any of these then this song may not be for you.
As far as powerful songs go I always love The Raven King and Honor The Fire by Killing Joke off of their Absolute Distant album

The Roots have had consistently blown me away with some of their songs as well
I cant really think of anything that has blown me away recently though
