Christina's distinctive, powerful vocals helped put her on the musical map way back in 1999, with the release of her first bubble-gum pop album, Christina Aguilera. After winning the Best New Artist Grammy in 2000, Christina has been a permanent staple on the Billboard charts with her work on 2002's "Lady Marmalade," as well as her follow-up albums Stripped (2002) and Back to Basics (2006).Although absent from last year's Top 99 list, Christina Aguilera reemerged in 2006 a newly married woman and a matured singer/songwriter worthy of this year's No. 35 spot.
