"Tell me, tell me, tell me something I don't know," Selena Gomez [1] sings on the final cut on her debut album, "Kiss & Tell." Considering how closely the new set follows similarly situated tween-pop efforts by Miley Cyrus [2] and Demi Lovato [3], Gomez's fans might share the sentiment: It's not always easy to tell what distinguishes the work of this "Wizards of Waverly Place" TV star from that of her fellow Disney-factory females. That doesn't mean "Kiss & Tell" doesn't deliver its required payload of electro-rock delights. The song "Naturally" (produced by Mouse House regulars Tim James [4], Antonina Armato and SuperSpy) has a juicy and instantly memorable vocal hook, while the pop-punk title track expertly channels the good-natured sass of the Go-Go's [5] (no surprise, given drummer Gina Schock's co-writing credit). But if Gomez wants to outlast her current context, her music could use more of her in it.-Mikael Wood
