good god you like the same stuff as me.
(also lol rockband2)
Try stuff by Phoenix and some stuff by the Killers. Most of the stuff on the First Impressions of Earth album by the Strokes is good too.
I could go on.
One more thing, the rb2 version of Jagged Gorgeous Winter is different from the regular version. Look for "A Jagged Gorgeous Winter (Rock Band 2 mix)" on the album You are Underwater for the one from the game.
