"Roll up a joint," Kacey Musgraves sings and strums on this sweetly mischievous track off 2013's Same Trailer Different Park. Of course, there's that little added "or don't" thrown out next, but that's just for prosperity (or the FM stations). Still, the song saw plenty of trouble on country radio, with programmers balking at casual marijuana advocacy and the girl-on-girl imagery. Musgraves had the last laugh, though, playing the tune on stage at the Grammys in glow-in-the-dark cowboy boots next to a psychedelic cactus, and snagged the Best Country Album award. Far out, y'all.
