It varies but my most frequent playlists are heavy on Alice Cooper, Slayer, Rob Zombie, Testament, Megadeth, Anthrax, or Steve Miller, Lynyrd Skynyrd, CCR, The Who, and The Kinks.

There's a little King Diamond, Misfits, Black Label Society, Paradise Lost, Ozzy and various metal artists mixed in the first....Oh, and I also have pretty much everything Weird Al has ever done. That one also gets a lot of play. In most cases I prefer his version to the actual song.
