If you want to download some angry music, get some raised fist or cannibal corpse, for raised fist songs, running man is always a good one, and stripped raped and strangled is a good one by cannibal corpse, a little messed up though. You might also enjoy some mudvayne, not really that angry, but it is loud death blooms is a good one by them. Loser by static x is a good one, and system of a down has quite a few good songs that sound angry I suppose. Of course there is always slipknot which has songs like purity and wait and bleed, check out a few of those. Oh yeah and who could forget linkin park? a place for my head is a good one so is forgotten.
