Hot/cold, in/out, yes/no, up/down: really, Max Martin? Dude, that's all you have left? The hitmaking impresario helmed this latest single from pop invertebrate and doll model Katy Perry, which sounds even less like anything than did "I Kissed a Girl" and "Ur So Gay." Enjoying her shtick as the non-maverick maverick (wait, that sounds familiar), it's Perry's trick to slink into the Wait A Minute, This Sucks Superstore while no one's minding the counter and rob us all of our ability to judge this as the lazy music it really is. Even for widescreen, built-for-KISS FM pop. Oh, and her most recent trip to the same store? Yeah, Katy also bought an Auto-Tune upgrade chip and 135 lifesize Ryan Seacrest cutouts (complete with voice-activated yes man blather!), one for every media market in the United States.
