People are always trying to downplay Christina's success. Say Something is billed as a duet, not a song with a main artist and a featured one. It's just as much her song as it is A Great Big World's. The irony of a Ciara fan saying Xtina cant sell on her own when Lotus outsold Ciara and Your Body & Just A Fool both sold more than Body Flop did. In fact, Bionic sold more then Ciara's last three albums combined. Ciara is just a glorified Janet Jackson tribute singer.
