I prefer to work out in silence. Just the sound of a bar shaking and heavy breathing. Preworkout I like '100 Miles and Running' by NWA or some Happy Hardcore. Listening to bands like Rage Against The Machine, System Of A Down, or Linkin Park make me think of some hick with a shaved head, gotee, and tribal tatoo running down his outer calf; not working out.
My personal preferance is Marilyn Manson. I used Antichrist Superstar for my routine.
However I was in the gym yesterday, asked them to get rid of the AC-DC shit and put on my Rage Against the Machine CD. It was on about 30 seconds and this bitch from the cardio room complained (she was about 23yrs, not 73yrs).
I prefer Marilyn, Rage, Ailce and Pearl Jam.
Manson
