Ask Slashdot: What Music do you Code By?

Silas writes "I value music as an important part of the coding/debugging/designing process, and choosing what music to listen to while working on a given piece of code can be as subtle and interesting a process as choosing what data structure or regular expression to use. My personal selection varies from Mozart to Happy Rave, Dave Matthews Band to Enigma, but I'm interested to know what members of the larger coding community listen to when they're doing their thing, getting in the zone. What music do you code by?" Ah. I like nothing less than coding to a good progressive Drum 'N Bass song. What about you all?
