Christina Aguilera’s best-of album, Keeps Getting Better — A Decade of Hits, is released today (Tuesday, November 11th). The set features some of her biggest hits, including “Genie,” “Come on Over (All I Want Is You),” “What a Girl Wants” and “Lady Marmalade.” Also on the collection are different versions of Aguilera’s singles, along with new songs “Keeps Getting Better” and “Dynamite.” Aguilera had this to say about the new album.

“It’s a very different time in my life. And also where I’m at musically and the direction I plan on going for the next all-new material full studio album, that will hit next year — hopefully sometime in summer 2009 — was going in a very much more futuristic direction. And I kind of wanted to play into that by reinventing ‘Genie in a Bottle’and ‘Beautiful.’Sort of giving them new life in a completely different direction and giving people a sneak preview of what’s to come.”

The greatest hits album is available exclusively at Target stores and Target.com
