TEENAGE DREAM

Preceded by her second number one single on Billboard magazine's Hot 100, "California Gurls," Katy Perry's Teenage Dream is filled with dance-pop that made One of the Boys her breakthrough album, but this time there's a decidedly summer spin. Hitmakers like Greg Smith, Dr. Luke, Christopher "Tricky" Stewart, and even Weezer's Rivers Cuomo lend a hand for what Perry predicts "will be one of those records that is everybody's favorite guilty pleasure."
