R&B hunk Usher has scored U.S. pop chart history by claiming the third-largest jump to number one on the Billboard Hot 100 in history. The "Yeah!" hitmaker has stormed to the top from number 51 with his new hit "Love In This Club," which features Young Jeezy.

The track ends Flo Rida's 10-week reign at the top - the rapper's "Low" drops to two on the new countdown.

But Flo Rida's anthem also breaks records this week - it becomes the only track to claim 13 straight weeks at number one on the RingMasters chart.

Meanwhile, Chris Brown, Rihanna and Sara Bareilles all drop a spot on the new chart to claim the third, fourth and fifth spots, respectively, on the new chart.

The Oscars' Best Song is the countdown's highest entry - Glen Hansard and Marketa Irglova's "Falling Slowly," from the film Once, debuts at 61.
