And you thought her divorce merited just one angst-pop anthem. Katy Perry whiffed with her first Russell Brand-breakup ballad, the guitar-powered "Part of Me." (Revenge like that is a dish best served by Kelly Clarkson.) "Wide Awake," another cut from the deluxe edition of Teenage Dream, is more her speed: a mid-tempo ballad, with throbbing dance-pop production. Perry's A-team – Max Martin, Dr. Luke and Bonnie McKee – delivers the goods, packing "Wide Awake" with hooks and sealing the deal with a monster chorus. Choice lyric for the tabloid jackals: "Outta the lion's den/I don't have to pretend/The story's over now/The end."
