interesting...
first, I don't have headphones, I've got a little 5.1 system (yeah, center, 2 fronts, 2 rears and the subwoofer) for my computer gaming experience.
Second... I don't want music getting in the way of Mitsu's sound pack and banana's lovely voice coming over VOX!
That said... Rock and Roll by Led Zeppelin would be my song for going into a furball.
Or twist and shout by the beatles if I'm in a Zeke.
