What music do you listen to when you hack?

I listen to Rinse.fm (http://rinse.fm) incessantly for 8+ hours a day, it's got some of the best DJs in London for dubstep, house, grime, reggae, and everything in between. Always a solid listen.

Otherwise, usually anything instrumental. B.Lewis, Apollo Brown, and Pretty Lights have some great instrumental albums out now which cast a positive and productive vibe on my hack sessions.

Oh, and people apparently enjoy coding to my instrumental album! :) http://djmarmalade.com (free download, shameless plug).

Personally, I'm heavily entrenched in the electronica camp. Coding favourites include: Deadmau5, Daft Punk's Homework, RJD2, DJ Shadow, Battles, Trent Reznor's Social Networking Soundtrack, Crystal Castles, Holy Fuck.

Usually I'm in to the "4 on the floor" music like Techno and House. However, when it comes to coding, I venture into Drum&Bass and classical.
