TAYLOR'S TOPS: Taylor Swift 's "Mine" advances 2-1 on Billboard's Adult Contemporary chart, marking the star's third No. 1 on the survey.
Swift led for six weeks with "Love Story" beginning in June 2009 and for 14 weeks with "You Belong With Me" beginning in October last year.
All charts will be refeshed Thursday (Dec. 2) on Billboard.com.
Since the Adult Contemporary chart adopted Nielsen BDS monitored airplay data in 1993, Swift is one of just eight artists with at least three No. 1s. Three of the eight acts are female country singers: Shania Twain  has also collected three No. 1s and Faith Hill  has tallied four.
"Mine" previously reigned atop two sales surveys: Digital Songs (one week) and Country Digital Songs (nine). By topping Adult Contemporary, the song leads an airplay chart for the first time. "Mine" reached No. 2 on the airplay-based Country Songs list, No. 7 on Adult Pop Songs and No. 12 on Pop Songs.
As "Mine," the first radio single from Swift's Billboard 200 No. 1 album "Speak Now," crowns Adult Contemporary, country follow-up "Back to December" bounds 26-22 in its fourth week on Country Songs.
HERE COMES 'SANTA': Mariah Carey  logs the highest debut among her 29 career Adult Contemporary chart entries, as "Oh Santa!" dashes in at No. 12.
The start is the chart's highest since deSoL bowed at No. 6 with "Little Drummer Boy" the week of Dec. 17, 2005.
Carey's previous loftiest launch belonged to "Dreamlover," which began at No. 17 in 1993.
"Oh Santa!," which introduces Carey's second holiday album, "Merry Christmas II You," has already topped Billboard's Holiday Digital Songs chart.
THE MORE, THE MERRIER: Five additional seasonal songs enter Adult Contemporary: "Have Yourself a Merry Little Christmas," by Katharine McPhee  featuring Chris Botti (No. 23); "Shake Up Christmas," by Train  (No. 24); "Do You Hear What I Hear," by Susan Boyle  featuring Amber Stassi (No. 25); "Santa Claus Is Coming to Town," by Wilson Phillips  (No. 27); and, "Christmas Tonight," by Dave Barnes with Lady Antebellum 's Hillary Scott (No. 29).
Wilson Phillips had last charted on Adult Contemporary in 2004 when its remake of Fleetwood Mac 's "Go Your Own Way" reached No. 13.
