"Bloodmeat" by Protest the Hero. It starts out with the line "Heads will roll, throats will be slit, blood will flow like springs of water." Good angry music.
If you're angry at a person, "The Good Left Undone" by Rise Against. Actually, just about anything by Rise Against. It's good, well written, high energy rock.
Also, "Knights of Cydonia" by Muse. Everyone has heard this, so I don't have to explain, but it's just awesome.
