BillboardBillboard will now be including catalog releases when calculating the best-selling albums, which were previously decided based on record sales from the past 18 months, reports Perez Hilton. The Nov. 25 chart will be the first to reflect these changes.

Taylor Swift is the only artist who sold more albums this year than Michael Jackson. Rihanna previously held the record for digital songs, selling 9.9 million, but Swift, Jackson, Lady Gaga and the Black Eyed Peas have all broken that this year.
