Susan Boyle repeats at No. 1

R. Kelly debuts at No. 4; Taylor Swift stays in the Top 10

The dream continues.

Susan Boyle, the frumpy, middle-aged Scot who grabbed international attention via YouTube and "Britain's Got Talent," holds at No. 1 for a second week on the Billboard 200. "I Dreamed a Dream" moved 527,000 copies in the U.S. during the week ending Dec. 6, according to SoundScan, giving her a jaw-dropping two-week tally of 1.2 million and becoming the 10th-best-selling album of 2009.

That was enough to fend off a serious challenge from Andrea Bocelli, whose "My Christmas" continues to surge during its fifth chart week. The holiday record sold 428,000 units, up 97% compared with the previous week and topping the 1.1 million mark. With Christmas looming, the set figures to continue building and could challenge 1999's "Sogno" (2.5 million) to become the Italian tenor's second-biggest album behind 1997's "Romanza" (4.2 million).

The week after Thanksgiving typically is a bit quiet on the big chart, as most major releases arrive before the holiday. The only debut in the top 10 this week is R. Kelly's "Untitled," which bows at No. 4 with 114,000 scanned. All nine of his solo studio sets have reached the top four positions on the chart, stretching back to "12 Play" in 1993.

Elsewhere in the chart's upper echelon, Taylor Swift's "Fearless" (No. 3, 127,000) spends its 47th week in the top 10, and Michael Jackson's "This Is It" (No. 8, 75,000) returns to the top tier after dropping to No. 11.
