The Servant - Cells (think Sin City trailers, utterly badass)
Dan Bern - Tiger Woods ("I got big balls, big ol' balls, big as grapefruits big, as pumpkins, yessir, yessir")
Sparks - This Town Ain't Big Enough For The Both Of Us (the title says it all)
Survivor - Eye Of The Tiger (I second Vince on this one)
The Caesars - Jerk It Out (I think this was in the old iPod Shuffle commercials)
Immortal Technique - Fuck You (...not my favorate song, but it gets the blood flowing)
Probably more, but yeah... those are some good ones.
