British music is the best
British:
Iron Maiden, Black Sabbath, David Bowie, Peter Gabriel, Pink Floyd, Queen, UNKLE, Radiohead, The Stone Roses, Ian Brown, Massive Attack, The Chemical Brothers, Blur, Public Image Ltd, Muse, Bloc Party, Kasabian. Oh, and of course The Beatles.
American:
Kings of Leon, Foo Fighters, Tenacious D, old Red Hot Chili Peppers (they've wussed out in recent years), Interpol, umm... hmm... yep- I like way more British artists.
My favorite newer band to come along in years is Australian, though! Wolfmother.
What I can't stand are all the bland "indie" bands in the UK who all sound exactly the same: Keane, Snow Patrol, The Kooks, etc. I've stopped listening to the radio because of them.
