Just checked the Grammy list, because I thought it was for the album, not the song.
Once again, MK has managed to surprise me! Isn't it ironic that it's in the category of "American Roots Music"?
I mean, there's nothing American in the song (apart from some of the player and the strats, of course), and the bridge on the cover is very obviously not Brooklyn Bridge, but still he's perceived as American somehow. Mysterious, again...
Edit: The other thing that mystifies me is that I don't know a single soul of all those other artists in the list. Maybe I'm not ahead of the game anymore ;-)
