Belle and Sebastian's "If You're Feeling Sinister" was in my CD player for like 6 months straight. The funny thing is that if you were to describe them to me, I'd have refused to listen to them, but they're really great...
Lately I've been listening to a lot of Old Time Radio (of course), but I'm really liking for new bands TV On the Radio, Of Montreal, Regina Spektor (especially "Maryanne Meets the Gravediggers"), the 2nd disc of the new Kate Bush record (though the first disc is kind of terrible), the new Polyphonic Spree (Great American July 17th! One of my favorite live bands ever!) is not bad and much darker than their previous two... etc.
