Billboard Changes Sales Calculations

After only including releases from the previous 18 months to calculate the best selling albums on the Billboard chart, Billboard will now be incorporating catalog releases due to the massive sales of both Michael Jackson and The Beatles.

The sales chart on November 25 will be the first official comprehensive chart.

In digital music news 4 artists have already broken Rihanna‘s track sales record of 9.9 million digital songs in 2008 including Michael Jackson, Lady Gaga, the Black Eyed Peas and Taylor Swift.

But the biggest news is probably that Taylor Swift is the only artist that outsold Michael Jackson this year in album sales!

That’s a mighty big accomplishment, T-Swizzle! Congratulations!
