Somethin’ Bad-Miranda Lambert / Carrie Underwood (RCA)

The snowball continues to roll and the format is now clearly the new Rock, with little bits of ‘real’ Country edging it’s way onto playlists from time to time. This song exploded online after their performance on the awards show and within a week of being posted. It’s now the 2nd biggest jumper in the digital world. and is the #1 selling Country single. It comes in at a nice, tight 2:45. Smart.
