Cher Lloyd (19) got her start on the UK's pop talent competition The X Factor back in 2010, and although she didn't win the ultimate competition, Cher's place as a finalist certainly helped kickstart her career.

"Want U Back," The third single off her US debut album is just as catchy as pop music gets. And the little Grrrrs she sprinkles throughout make it extra special. It's a guilt pleasure song. Enjoy it, darling.
