Bionic (Deluxe Version)

Christina Aguilera’s musical omnivorousness is at the heart of Bionic, a sprawling, guest-laden album that shows how her forceful voice can handle wounded balladry (the soul throwback “You Lost Me”) as well as glitchy electro-pop (the storming “Not Myself Tonight,” the featherlight “Glam”) and bed-headed come-ons (the swirling “Sex for Breakfast”). On the breezy “My Girls,” Aguilera lets her hair down a bit, delivering one-liners over gently swaggering beats alongside electro provocateur Peaches. A confident, at times surprising collection of new-generation pop.
