Hmmm, lets chuck a few different bands and artists into this mix. This list is composed of entirely British music, (with the exception of Feeder's bassist, Taka Hirose being, funnily enough, Japanese,) For me, I listen to things such as the following:
Ash: Burn Baby Burn - a must for elemelee farming, not just budding pyros

Ash: Orpheus - the same, really fires up the adrenaline
Arctic Monkeys: Bet You Look Good On The Dancefloor. Another energy burner.
Kaiser Chiefs: I predict a Riot: For charging griffons and Leeeeeeroy Jeeeenkinsss moments

Franz Ferdinand: The Fallen - 'Some say he's a troubled boy, just because he likes to destroy,' what more can I say?
Feeder: Buck Rogers and Just a Day. I bought Feeder's recent albums on the strength of these tracks. I got pwnt lol
Plenty more I could mention, but I'd be here all day if i did.
But of course, when all else fails and hope is lost:
Jonny Cash: Ring of Fire, the ultimate musical depression cure
