Didn't SPIN magazine dub Rilo Kiley the new FM on their cover?
There are a ton of popular indie artists out there who are constantly compared to Fleetwood Mac (not as a whole, but a song or two):
Midlake
Fleet Foxes
Bat for Lashes
The Decemberists
Have you heard M Ward's new album? It's very Tusk-ish. "Never Had Nobody Like You" is getting lots of airplay here, the fuzzy guitar sounds alone are very Lindsey-ish.
I've always thought the rhythm/bass line of Iron & Wine's "Boy With a Coin" sounds like Illume.
