Fifteen years ago this month, Christina Aguilera successfully shed her Disney image with her sultry self-titled debut album, a No. 1 hit and a game-changing moment for the former "Mickey Mouse Club" star. The following decade-and-a-half has been full of such reinventions for Aguilera, who has gone from bubblegum queen to dirrty diva to "Beautiful" balladeer to, most recently, all-star guest artist, helping artists like Pitbull and A Great Big World achieve chart success. Throughout her career, one constant has remained: a powerful, wholly unique set of pipes that, when paired with the right arrangement, can still blow Top 40 listeners away.
