Josh Groban’s Christmas album Noel, which was released only 10 weeks ago, has now surpassed the High School Musical 2 soundtrack to become to best selling album of the year. Selling almost 2.8 million albums, it beat out High School Musical 2 which had sold 2.7 million, and Chris Daughtry (of “American Idol”), whose debut album Daughtry sold 2.3 million.

Noel is the first Christmas album to spend four weeks in a row at the top of the charts, and only the second Christmas album to spend that many weeks at #1 at all (after Elvis’ 1957 Christmas album). It’s also the first album to experience an increase in sales each week at #1 since No Doubt’s 1995 album Tragic Kingdom.
