Over the past two weeks, a handful of the biggest female pop stars in the world have previewed their forthcoming albums with winning, radio-ready singles. Christina Aguilera, Taylor Swift, Ke$ha and Rihanna all have new songs with their own individual charms -- but which new single is the cream of the fourth-quarter crop?

Vote now in the poll below to tell us which female superstar -- Christina, Taylor, Ke$ha or Rihanna -- has released the month's all-star radio track.

First came the return of Christina Aguilera, who just wanted to love "Your Body" in the first taste of her "Lotus" album. Then, Taylor Swift followed her Hot 100-topping "We Are Never Ever Getting Back Together" with "Begin Again," a new single that finds the country star moving on from a rocky relationship.

Ke$ha stepped back onto the scene with "Die Young," an electro-pop swirl that promises to live a long time on our charts. And finally, Rihanna followed up her string of successful "Talk That Talk" singles with "Diamonds," a mid-tempo anthem from her forthcoming seventh album that finds the Barbadian star telling her listeners to "Shine bright like a diamond" over a beat produced by Stargate and Benny Blanco.
