After reigning over the Pop Clash for three weeks, Taylor Swift lost her title to the new champ, Cher Lloyd! Cher's 'I Wish' is taking over the radio, but does it have enough momentum to ward off Britney Spears' 'Work Bitch'?

Props to Cher Lloyd. When she feels insecure -- she owns it! In 'I Wish,' the pint-sized singer waxes poetic about everything she doesn't have. Cher may rock Nikes instead of five-inch heels, but she does have one thing: T.I. collaborating on her track!

Britney Spears is making it clear that, in no uncertain terms, she's back. 'Work Bitch' is a dancey track that celebrates Brit's empowerment. The song echoes a sentiment the singer knows well: working hard to get what she wants. While Cher is listing the things she wants, Brit takes it further and advises her listeners just how to succeed.
