Thanks to the success of One Direction, Simon Cowell is searching his stable of British "X Factor" recruits for other possible American stars. He's picked Cher Lloyd, an 18-year-old rapper-singer who comes across as a kinder, gentler Lily Allen on her new single "Want U Back" (Syco). It's pretty standard-issue pop, aside from her British accent and the way they try to turn her growl -- suitable for Wimbledon tennis courts -- into some sort of percussion. You wouldn't think that would be enough for a hit, but such is the power of teenage girls.
