I don't have anything that's really calling out to me that I have to buy.

I give half-hearted looks at The Wolf Parade, when in my local store, but the pull isn't very strong. A friend played a disc from a band called Kasabian this weekend, that sounded interesting, and there's that one that Davey and Jim have mentioned as sounding more like Interpol, than Interpol, can't recall the name right now. Elbow is a possibility, but their first release didn't get that much playing time so they may not warrant another look. Should probably get some long-overdue follow-ups to first purchases from the likes of Pinback and Idlewild.
