Ultimate Metal/Hardcore/Prog Workout Playlist

appleseeds

I'm in serious need of some new music.
I was wondering what's on your workout playlist?
Maybe if it's similar to mine you'd have some suggestions.

Mine includes;

Glassjaw
Textures
Strapping Young Lad
Deftones
Between the Buried and Me
Alexisonfire


Seriously though - with the exclusion of BTBAM, I've been listening to these bands since high school. Suggestions?
The more brutal the better.
