Rapper FLO RIDA continues to ride high at the top of the U.S. singles chart - his smash hit Low has claimed a ninth week at number one on the Billboard Hot 100. Low again keeps Chris Brown's With You and Rihanna's Don't Stop The Music stuck at two and three respectively. Alicia Keys is another non-mover at four with No One, while Sara Bareilles' Love Song climbs a place to five. Mariah Carey's Touch My Body is the new chart's highest debut at 57.
