Here's something fun: post your shortest and longest song in your starred/main playlist.
Dog the Bounty Hunter Theme by Ozzy Osbourne - 0:53
Alive 1997 by Daft Punk - 45:31
EDIT: I kinda cheated since Alive is a concert not a song per se, the longest song is actually 'Horsell Common And The Heat Ray' by Jeff Wayne - 11:36
