This is a cool song: Ain't No Rest For The Wicked by Cage The Elephant

Epic! I loved it in Borderlands too. (Man, the intro beats of this song is HELLA funky!)

I hear this song over and over when i'm sitting on Borderlands' menue modding my saves on Willowtree.

The credits end song is pretty good too.
