Some things by Cradle of Filth, very heavy HEAVY guitar, can't understand the guy and they are Satanic. But if they can't get your blood boiling nothing will, look up Lord Abortion if you are interested, or Suicide and Other Comforts.
Powerman 5k, Drowning Pool, Otep, Soil. Tons of stuff, especially somethings by System of a Down.
Sometimes Slow Industrial like Stabbing Westward gets me pumped, slow and depressing and just gets me in the zone to pound. Other times it takes heavy guitar and deep screaming like Cradle of Filth. Music makes a big difference in my lifts, it is like a NOS Product to me, especially when the gym is playing Car Wash and other shit like that.
