Cardio Metal Soundtrack

I have a little Ipod shuffle I listen to on random at the gym, I usually use it as an opportunity to listen to stuff I might not otherwise. I have a ton of stuff in my Itunes that I like, but I know I probably wouldn't listen to it much if I put it on my main Ipod, so I try to put it in rotation on the shuffle. Right now I think I have Cannibal Corpse, Psycroptic, Cattle Decapitation, Hatesphere, Soilwork, Darkane, Machine Head and a few others
