I am a fan of, both, Tool and APC. Mayanard is quite talented on both fronts. I like the older stuff from NIN. Haven't really listened to the new stuff except their radio single "The Hand That Feeds" which I thought was a bit of a departure from their usual style but still good nonetheless.
Cradle of Filth and Lamb of God are bands I enjoyed listening to in high school along with Vision of Disorder. After a heavy night or drinking in college, I'd use one of those CDs as my morning alarm. Got me up every time heh.
