Another impressive DJ that caught my eye during the YouTube Live event: Mike Relm. I haven't heard all his stuff but his mixing on Live was pretty impressive.
I certainly can, in fact I've found it to be rather good coding music.
Then again, I also find Lighning Bolt, Slayer, and Merzbow to be good stuff to listen to while coding. Merzbow especially helps me get in "the zone".
Also: Shpongle, Squarepusher, Aphex Twin, Q and not U. Godspeed You! Black Emperor, Explosions in the Sky, Mogwai, American Analog Set, Fugazi, Fuck Buttons, Radiohead, and a million other bands / musicians I can't remember right now.
