NEW YORK (Billboard) - Rookie rapper Flo Rida led the Billboard Hot 100 singles chart for a seventh week Thursday, although R&B singers Chris Brown and Rihanna were mounting strong challenges.

If Flo Rida's "Low" is still No. 1 next week, it will be the longest-running chart-topper since Beyonce's "Irreplaceable" held sway for 10 weeks in 2006 and 2007.

Brown's "With You" rose one to No. 2, and Rihanna's "Don't Stop the Music" jumped two to No. 3. Timbaland's "Apologize" featuring OneRepublic held at No. 4, while Alicia Keys' "No One" fell three to No. 5. Keys did, however, return to the top of the Billboard 200 album chart Wednesday with "As I Am."

Sara Bareilles' "Love Song" rebounded three to No. 6, Fergie's "Clumsy" slipped one to No. 7, and Snoop Dogg's "Sensual Seduction" remained at No. 8.

The biggest news in the top 10 was the No. 9 debut of French-born, Israeli-raised female pop singer Yael Naim's "New Soul," a song heard in the TV commercial for the latest Apple laptop, the ultra-thin MacBook Air. It is the chart's best entry since "What Time Is It" by High School Musical 2 Cast (No. 6) and Akon's "Sorry, Blame It on Me" (No. 7) bowed in the same week last August.

Sean Kingston's "Take You There" dropped three to No. 10 to round out the top tier of the Hot 100.
