Off the top of my head, here are some indie pop bands that I've been listening to lately:
Mahagony - Think of an indie pop interpretation of the 1920's ideal of the future, I guess.  Sort of like Architecture in Helsinki, but less spastic and more clockwork dreamscapes.
Jens Lekman - Great Swedish singer songwriter, emphasizing the 
pop part of indie pop.  He has a new album coming out next month, which I haven't heard yet, but you might as well out what's there, right?  I think his best two are 
Oh You're So Silent Jens and 
Rocky DennisActually, why don't I just send you here:

Little Darla Has a Treat for You compilations, which were a good way to find new bands, but it's so much easier with internet magic.
