It's almost September (it already is on the Hot 100, which is dated over a week ahead of time), and the labels are starting to roll out the medium-sized guns: Muse! The Script! Trey Songz! Slaughterhouse? The best stuff is older, though: The Chief Keef track is from a mixtape released in March, and the Eric Church and Luke Bryan tracks are both over a year old and milking best-selling albums. None of this week's entries is great, and three of them are awful (guess), but the fall season has officially started. Don't forget to duck.
