Song of the Day #221 - i don't know whether i'm the boxer or the bag

Saw 50/50 tonight and this played during the closing credits. Definitely in the conversation for best Pearl Jam song.  Can't believe it's only a b-side.  Also, the only reason I know those are actual lyrics in the song is because I looked it up.  Oh, Eddie Vedder and your unintelligible lyrics....

Pearl Jam - Yellow Ledbetter

ps - really liked the movie, by the way
