Beyonce's "Irreplaceable" begins a third week at No. 1 on the Billboard Hot 100, and also sits at No. 1 on the Pop 100 for a second week and Hot R&B/Hip-Hop Songs for a fourth. The track had been the Hot 100's greatest airplay gainer for six weeks, but that distinction is claimed this week by Ciara's "Promise," which rises 14-11.

The top tier of the Hot 100 doesn't show much movement, as Akon's "I Wanna Love You" featuring Snoop Dogg holds at No. 2 and his "Smack That" featuring Eminem inches up 4-3. Fergie's "Fergalicious" slips 3-4, while Justin Timberlake's "My Love" featuring T.I. remains at No. 5 and Nelly Furtado's "Say It Right" stands firm at No. 6.

The top 10 is rounded out by Jim Jones' "We Fly High," up 8-7, the Fray's "How To Save a Life," up 9-8, Bow Wow's "Shortie Like Mine" featuring Chris Brown and Johnta Austin, up 10-9, and Hinder's "Lips of An Angel," which creeps 11-10.

The chart's top debut this week is a cover of John Lennon and Yoko Ono's "Happy X-mas (War Is Over)" by the Fray, which opens at No. 50. The original was released in 1971 but had never previously charted on the Hot 100. The same song enters the top 10 of the Adult Contemporary tally this week at No. 7, in a version recorded by Sarah McLachlan.

Other Hot 100 debuts this week come from Fall Out Boy's "The Carpal Tunnel of Love" (No. 81), AFI's "Love Like Winter" (No. 88), Gwen Stefani's "The Sweet Escape" featuring Akon (No. 93), Josh Groban's "I'll Be Home for Christmas" (No. 95), Regina Spektor's "Fidelity" (No. 98) and Baby Boy Da Prince's "The Way I Love" featuring Lil Boosie (No. 100).

On the Hot Latin Songs chart, Ricky Martin's "Tu Recuerdo" featuring La Mari begins a second week at the top, while Sugarland's "Want To" holds at No. 1 on Hot Country Songs for a second frame.

Billboard's rock roundups are unchanged, as Incubus's "Anna Molly" and Three Days Grace's "Pain" move into a second week atop Modern and Mainstream Rock, respectively.

And for the first time in the seven years that holiday songs have been rising to the top of the Adult Contemporary chart, two Christmas tunes have advanced to No. 1 in the same holiday season. Last week, Kimberley Locke's version of "Jingle Bells" planted a flag at the summit. This week, Daryl Hall and John Oates' version of "It Came Upon a Midnight Clear" is the new champ.
