We're not sure how to feel about this: A new video is floating around that's half music video, half ad for Chipotle. On the one hand, the soundtrack is Willie Nelson doing a very lovely, spare version of Coldplay's "The Scientist." On the other hand, it's a big, schilly ad for a giant fast-food chain. We can get over any reservations we're feeling, since Willie is obviously the awesomest, and he's a huge part of Farm Aid. Anyway, watch the clip below and decide for yourself, then buy the song on iTunes if you're feeling so inclined. And be prepared to have the song stuck in your head for the rest of the afternoon.
