Lady GaGa ascends 2-1 on the Billboard Hot 100 this week with "Just Dance," which sold 279,000 downloads in the United States, according to Nielsen SoundScan. At 22 weeks, the song makes the longest trip to the top since Creed's "With Arms Wide Open" (27 weeks) in November 2000.

For the first time since Jan. 17, 1998, the Hot 100 does not have a debut; the only additions to the list this week are re-entries. Last week's No. 1, Beyonce's "Single Ladies (Put a Ring on It)," drops to No. 2, while T.I.'s "Live Your Life" featuring Rihanna holds at No. 3.

Kanye West's "Heartless" drops 4-5, Katy Perry's "Hot N Cold" remains No. 6 and Jason Mraz's "I'm Yours" rises 12-7. Britney Spears' "Womanizer" is down 7-8, Kevin Rufolf's "Let It Rock" featuring Lil Wayne climbs 12-9 and another West song, "Love Lockdown," slides 6-10.

On Hot R&B/Hip-Hop Songs, "Single Ladies" is No. 1 for an eighth week, while Sugarland assumes control on Hot Country Songs with "Already Gone," which flip-flops 2-1 with Rascal Flatts' "Here."

There's no change on Billboard's rock charts, with Kings Of Leon's "Sex on Fire" starting a fifth week atop Modern Rock and Shinedown leading Mainstream Rock for a fourth with "Second Chance."
