7. Beyoncé Knowles
After a triumphant, showstopping performance at the 2013 Superbowl Half-Time Show, the world has truly been overcome with Beyoncé fever. Last week saw 4, Beyoncé's most recent studio release, return to the UK album charts - as well as DVD sales of Obsession reach an all time high of 6 copies. Billboard also report that tickets for the singer's Mrs. Carter tour are selling out fast, with the demand being described as "massive". Surely the above are all indicators that Beyoncé is set to rocket to the top of the charts when her new material (which the star has described as "sensual" and "empowering") does surface. The singer's biggest challenge is surely that of topping 4, so if any of these new tracks reach the glorious highs of Schoolin' Life or Countdown, pop fans worldwide will be ecstatic. http://www.youtube.com/watch?v=oAmnkPUFMHg
