Christina Aguilera “Bionic”
Standouts - “I Hate Boys,” “Lift Me Up,” “All I Need”

“Bionic,” the 29-year-old’s fourth studio release, is a disappointing album that will have listeners asking: Will the real Christina Aguilera please stand up? The CD’s lead single, the Polow da Don-produced “Not Myself Tonight,” is mediocre at best, with its leather-and-chain styled music video that screams hot mess. Aguilera recruited of a number of top producers and songwriters for “Bionic,” and the results vary. When Aguilera sings on the futuristic "Elastic Love," co-written by M.I.A., she proves she doesn’t have enough swag to pull the song off, but she wins you over on the Linda Perry-assisted “Lift Me Up.”
