One and a half words: Brainstorm.
Absolutley!
Who the f**k are Arctic Monkeys?
No thanks.
Somehow I ended up with the Whatever You Say I Am... album on my iTunes library (seriously, I have no idea how). I'd never heard of Arctic Monkeys before, but after listening to the album a few (dozen) times in the last month, I'd love to have a few of their songs in Rock Band.
If they came out with a 3-pack with Dancefloor, Brianstorm, and Certain Romance I would probably poop my pants. Well, I would more than likely do that anyways, but at least now there would be a reason for it. In all seriousness, they could easily put out a full album DLC for Whatever People Say. It's that solid.
