Beyonce's "Irreplaceable" continues to reign as the dominant song of December, as it moves into a fourth week at No. 1 on the Billboard Hot 100. The track is also No. 1 on Hot R&B/Hip-Hop Songs for a fifth week and the Pop 100 for a third. Beyonce also has the Hot 100's top debut with "Listen," which opens at No. 95.

"Irreplaceable" rules a relatively static top tier of the Hot 100, which finds Akon's "I Wanna Love You" featuring Snoop Dogg holding at No. 2 and Fergie's "Fergalicious" inching up 4-3. That track swaps places with Akon's "Smack That" featuring Eminem, while Justin Timberlake's "My Love" featuring T.I. remains at No. 5 and Nelly Furtado's "Say It Right" stays put at No. 6.

The Fray's "How To Save a Life" rises 8-7, followed by Bow Wow's "Shortie Like Mine" featuring Chris Brown and Johnta Austin at No. 9 and Hinder's "Lips of an Angel" at No. 10. The All-American Rejects' "It Ends Tonight" climbs 18-11 and is the chart's top digital gainer, having shifted 26,000 downloads.

Ludacris' "Runaway Love" featuring Mary J. Blige jumps 31-22 and is the chart's fastest growing track at radio. Elsewhere, KT Tunstall's "Suddenly I See" re-enters the Hot 100 at No. 43 thanks to digital sales of 23,000. The track peaked at No. 45 earlier this month.

Besides "Listen," the only other debut on the Hot 100 this week at No. 97 is Pretty Ricky's "On the Hotline," the first single from the group's upcoming Atlantic album, "Late Night Special."

On the Hot Latin Songs chart, Ricky Martin's "Tu Recuerdo" featuring La Mari begins a third week at the top, Brad Paisley's "She's Everything" swaps places with Sugarland's "Want To" on Hot Country Songs, climbing 4-1. The song is Paisley's seventh No. 1 on this chart.

Billboard's rock charts don't change, as Incubus's "Anna Molly" and Three Days Grace's "Pain" move into their third weeks atop Modern and Mainstream Rock, respectively.
