The Smurfs sequel, smartly named The Smurfs 2, may star (the voices of) Katy Perry and Neil Patrick Harris, but it also will include a new, PG-rated track from Britney Spears. Recently departed from the set of The X Factor, Brit's got the likes of will.i.am on her side, and is reportedly back in the studio. Movie's out July 31 and "Ooh La La" is undeniably reminiscent of "I Wanna Go," with a little Ke$ha influence thrown in there. She raps! Well, actually, she speaks: "Turn it up till the speakers pop." Go ahead, do it.

Right after two super-sexy singles, Kelly Rowland's newest, "Dirty Laundry," certainly airs just that. Produced by The-Dream and laid over a sparse track, this confessional speaks of everything from a troubled relationship with former bandmate Beyoncé ("When my sister was on stage killin' it like a motherfucker / I was enraged, feelin' it like a motherfucker /Bird in a cage") to an abusive relationship with an ex ("He hit the window like it was me, until it shattered"). You probably won't hear this on the radio, but it's a good one.

Prince is such a fountain of perfect pop songwriting that artists like
Sinead O' Connor and Chaka Kahn have been able to have giant hits covering his unreleased song and random album tracks. Another example is the Bangles, whose breakthrough hit "Manic Monday" was originally penned by Prince for Apollonia 6. (Though it could've also worked for Garfield the cat.) Well, the originally demo has been making the rounds, and it's some really good stuff. Especially because it makes you realize the verse's melody is basically identical to "1999." Listen below, it will make today your funday.
