M&Ms at such great heights!

I was surprised to hear an acoustic version of "Such Great Heights" by the Postal Service (actually performed by Iron & Wine, but available on the Such Great Heights EP) used in an M&M's commercial. It's the one that goes:

I, I'm thinking it's a sign
that the freckles in our eyes are mirror images
and when we kiss they're perfectly aligned

when multicolored M&M's are displayed on the screen.

Not only is The Postal Service not that popular (very popular for a synthesizer-based band, but hardly burning up the charts), they're a relatively new band. I'm impressed their music made it into a commercial so quickly!
