Scoring big in the yuletide run-up, Michael Buble’s “Christmas” maintained its hold on the No. 1 position on the U.S. album chart despite a formidable holiday surge by Adele’s bestselling “21.”

Buble’s Warner Bros. collection topped the list for a fifth consecutive stanza with sales of 467,000, up 4%, according to Nielsen SoundScan data for the week that ended Christmas Day.

Total sales for “Christmas” of 2.4 million are second only to “21” among 2011 releases. But Brit thrush Adele’s Columbia collection remained puissant in the late going, notching its best sales week with a 399,000-copy frame, good for No. 2. Album debuted in March with a 352,000-unit week.

Adele’s set is the year’s undisputed sales champ with nearly 5.7 million sold to date and could log another week at No. 1 next week as Buble’s holiday title loses steam.

Just six titles sold in excess of 100,000 during this year’s Christmas shopping rush vs. 11 that topped that level the same week in 2010, but the strong performances of the Buble and Adele titles helped balance the books.

Pre-Christmas shoppers embraced a late-breaking rap title: Young Jeezy’s “TM 103: Hustlerz Ambition” (Def Jam) bowed at No. 3, moving 233,000. It’s the Atlanta-bred performer’s fourth consecutive top-five entry.

Week’s other six-figure performers were Justin Bieber’s “Under the Mistletoe” (No. 4, 225,000 sold, up 32%), Drake’s “Take Care” (No. 5, 131,000, up 71%) and Lady Antebellum’s “Own the Night” (No. 6, 110,000, up 36%).

Two titles separated by just 70 copies barely missed topping 100,000: Rihanna’s “Talk That Talk” (No. 7, up 83%) and Nickelback’s “Here and Now” (No. 8, up 23%) both tracked around 99,000 units.

The Black Keys’ “El Camino” (No. 9, 92,000, up 9%) and the “Now 40” hits compilation (No. 10, 88,000, up 38%) complete the top 10.

Next Wednesday, SoundScan will release 2011’s year-end figures, which are expected to reveal the music biz’s first sales increase since 2004.
