What kind of music/which songs do you like to listen to when working out? I'm always on the lookout for new stuff....some of mine:

Black Crowes - Go Faster (obligatory)
Buckcherry - Lawless and Lulu
The Mars Volta- L'Via L'Viaquez (kinda intense)
Bon Jovi- Bad Medicine (cheesy 80s butt rock, but you gotta love it!)
