Sirius- Octane and Blue Collar Comedy. Sometimes Lithium and Liquid Metal.
Have the new Metallica, its ok. Also Atreyu, Bullet for my Valentine, Motley Crue. I really only buy CDs, and only if theres stuff I can drum to.
Honestly, it depends on my mood. With my musician background, I'll listen to anything from Boston Pops to Pantera and everything in between. I end up listening to a general Pop/top 40 station at work, just because its local and all I can pick up in my concrete bunker of a receiving dock. Wish I could take the Sirius with me, but tried already and couldn't get a signal at all. Cell phones don't even work in there.
