Which Music Superstar Just Beat the King?

Mariah Carey now has more #1 singles than Elvis Presley -- and she's now second only to the Beatles. Her 18th hit "Touch My Body," from her new album "E=MC2," just helped her make history.

"I really can never put myself in the category of people who have not only revolutionized music but also changed the world," she told the AP. "That's a completely different era and time ... I'm just feeling really happy and grateful."
