Rapper Flo Rida still No. 1 on U.S. singles chart.

Rapper Flo Rida's debut single led the Billboard Hot 100 singles chart for a 10th week on Thursday, the longest reign in more than a year. "Low" ties Beyonce's 2006/07 chart-topper "Irreplaceable" and Kanye West and Jamie Foxx's 2005 hit "Gold Digger" as the longest-running champ since Mariah Carey's "We Belong Together" led the pack for 14 non-consecutive weeks earlier in 2005
