NEW YORK (Billboard) - British R&B singer Jay Sean's single "Down" returned to the top of the Billboard Hot 100 on Thursday, just a week after Britney Spears' No. 1 debut bumped him to runner-up status.
In its second week, Spears' suggestive "3" slipped to No. 5 on a drop in digital sales, even as radio play continued to blossom.
Between Sean and Spears, Jason DeRulo's "Whatcha Say" climbed from No. 4 to No. 2 on the singles chart, leapfrogging Miley Cyrus' "Party in the U.S.A.," which remained at No. 3.
"Run This Town" by Jay-Z, Rihanna and Kanye West moved up one to No. 4.
Lady Gaga rebounded one rung to No. 6 with "Paparazzi," and singer-songwriter act Owl City continued to soar, with "Fireflies" jumping from No. 9 to No. 7.
The Black Eyed Peas occupied the next two slots in the top 10 with "I Gotta Feeling" (down two to No. 8) and "Meet Me Halfway" (rising from No. 17 to No. 9). Sales of "Halfway" were buoyed by the track's iTunes video premiere and its inclusion in the latest television spot for DirecTV, shown frequently during the MLB Playoffs on TBS and FOX.
Closing out the top 10 was Taylor Swift's "You Belong With Me" (up two to No. 10).
John Mayer scored his best Hot 100 debut at No. 17 with "Who Says," the opening single from his upcoming album, "Battle Studies," due October 27.
Chamillionaire was back on the Hot 100 as a lead artist for the first time since he topped the list with "Ridin" in June 2006. His new single, "Good Morning," debuted at No. 40.
Also entering the chart were two more tracks from the TV series "Glee" -- "Keep Holding On" and "No Air" at Nos. 56 and 65, respectively. South Korean pop quintet Wonder Girls made its first U.S. chart appearance with "Nobody" at No. 76.
