Breakfast Topic: Music to play by

I've been listening to this song a lot while playing World of Warcraft this weekend. I'm not going to stand here and pretend it's some kind of masterpiece -- it's nü-metal, not Holst. But one of the things it does very well is get me hyped to hit buttons. Like, you have no idea how much faster I can spam buttons with this thing going. Does that produce any real, measurable result? Absolutely it does not. And yet, running WSG or Alterac Valley or Strand of the Ancients is just more fun for me with this playing. Every ridiculous pitched battle over a flag, every mass of bodies trying to capture a tower, every running fight over whether or not a demolisher will get to a gate is more fun for me with this hyperkinetic thing playing in the background.

Usually I just listen to the in-game music, too. So I'm wondering -- which works better for you? Which feels better? Do you have song lists? Do you listen to in-game music, turn all sound off, or blast your favorite tunes while you play? Do you listen to music only when you PvP, like I do? What're you doing with your ears while you play?
