Heh, so the music I listen to tends to be pulsing non-vocal quiet electronic music (currently listening to: Done by Robot Science) because it's not music I'm going to sing or sitting-dance along too, and it's entirely ignorable, but it also cuts out the noise of everything around me.

I can still see my coworker hacking SQL into some XML (wtf is he doing) out of the corner of my eye, but I'm not sure wearing horse blinkers to work would be socially acceptable.
