Any good rock/alternative bands like the ones listed?

lol. my itunes has nearly every one of those artists. You should really check out Bloc Party, Rage Against the Machine, The Decemberists, The Kooks (if you're into that sort of thing, i resent myself for sort of liking them), The Hoosiers, Kings of Leon, Muse (awesome awesome band), The National, The Racontuers ("broken boy soldier" is a great song by them. and the lead singer sort of sounds like that guy from Wolfmother) and TV on the Radio.
