The Daily Grind: What is your MMO soundtrack?

We know that you MMO playing folks tend not to listen to the in-game music (which this blogger thinks is a real shame), but you have to be listening to something while you play. Dead silence is pretty darn boring. So, we're wondering what you do to amuse yourself while you're in-game. This blogger splits his time pretty evenly between podcasts and shows from Hulu.com when he does his daily quests. The Daily Show and the Isle of Quel'Danas go hand in hand like peanut butter and jelly.

Do you listen to nerd-core? Maybe some nice acapella? What do you listen to when you're doing your questing thing? What's blaring over the guild chat when you take down raid bosses? What is your personal MMO soundtrack?
