Hip-hop duo OutKast scores its second No. 1 single on Billboard's Hot 100 as "Hey Ya" moves up one this week. The track swaps places with "Stand Up!" by Ludacris and Shawnna, which falls to No. 2 after just one week at the top.

OutKast -- the Atlanta-based duo of Big Boi and Andre 3000 -- first topped the Hot 100 in 2001 with "Ms. Jackson." The Andre 3000-led "Hey Ya!" climbed to the peak of the chart in just nine weeks. It's also the chart's fastest-growing track at radio, marking the third time in five weeks the song has held that honor. Close behind "Hey Ya!" is the Big Boi-voiced single "The Way You Move" featuring Sleepy Brown, which gains 4-3 this week.

Meanwhile, R&B singer Kelis soars into the top-10 with "Milkshake." The song posts a 12-4 gain, giving the singer her highest career showing on the Hot 100. Kelis' third album, "Tasty," is due Tuesday (Dec. 9) in the U.S. via Arista and once again features production work from the Neptunes.

The only other track moving up the top-10 this week is R. Kelly's "Step in the Name of Love." The song, which hops 10-9 in its 17th week on the tally, also maintains its grip on top of Billboard's Hot R&B/Hip-Hop Singles & Tracks chart for the second week in a row. On that chart, the cut withstood a 5-2 gain from Alicia Keys' "You Don't Know My Name."

Country star Alan Jackson scores the week's top debut on the Hot 100 as "Remember When" opens at No. 61. The song moves 17-12 over on Billboard's Hot Country Singles & Tracks roundup, where Toby Keith's "I Love This Bar" is No. 1 for the fifth week in a row.

Other notable entries on the Hot 100 include Mary J. Blige's "Not Today" featuring Eve (No. 67), Terri Clark's "I Wanna Do It All" (No. 70) and Tim McGraw's "Watch the Wind Blow By" (No. 75).

Michael Jackson's "One More Chance" is the Hot 100's fastest-growing track at retail and is up 95-83 in its second week on the chart. The cut is the second-best selling single in the U.S., according to Nielsen SoundScan, behind "I Can Only Imagine" from MercyMe, which has led Billboard's Hot 100 Singles Sales chart for nine weeks.

Over on Billboard's Mainstream Rock Tracks chart, Puddle Of Mudd jumps 2-1 with its "Away From Me," as Trapt's "Still Frame" falls to No. 3. Meanwhile, Linkin Park leads Billboard's Modern Rock Tracks tally for a fourth week with "Numb."
