Christina Aguilera has two alluring anthems of pop femininity, "Genie in a Bottle" and "What a Girl Wants," but the remainder is generic Top Forty pop that sounds like she had not quite outgrown the sexless Disney mindset. 

 Fans of Aguilera had to wait three years for the skankification of their American idol: Stripped, decorated with images of the singer in varying states of piercings and undress, claims to be an honest self-portrait, "no hype, no gloss." 

 Unlike Janet or Britney, Aguilera's "grown up" album involved putting her clothes back on. Back To Basics replaced tweenie porn-pop with the cheescake smirk and brassy bravado of a classic Forties-era songstress. 

 Keeps Gettin' Better nabs Christina's singles with a few updated remixes and two new songs.
