Recommend some workout music

I need kick-ass music to workout to.

I did a search, and all I found was a thread about 80’s metal. (BTW, nobody mentioned that Kix ain’t just a cereal… but I didn’t want to resurrect an old thread.)
I don’t need ballads, just kick-ass, get your blood pumping music. The most perfect that I have found so far is Rob Zombie’s More Human Than Human. Metallica’s Fuel kicks ass as well. Any other suggestions?

Anything by Dragonforce! I’m no metalhead (far from it), but I can’t think of much better workout music.

The Transformers: The Movie soundtrack (the one from 1986, not the one coming this summer).

Rammstein. Start out with one of their first songs (also named Rammstein) to get an idea of what you can expect.

More Human Than Human, huh? In that vein, I’d recommend:

Back in Black by AC-DC
Zombie by The Cranberries
Cum Feel the Noize by Quiet Riot
Let’s Go All the Way by Sly Fox

Sepultura, Arise, Roots

*Pump it Up * - Elvis Costello.
