PENTATONIX XMAS ALBUMS LIGHT UP iTUNES (UPDATE)

UPDATE: 'Tis the season for Pentatonix's holiday catalog. The RCA group currently has four albums in the iTunes Top 20, led by their latest project, We Need a Little Christmas, which leapt to #1 on Wednesday (12/9) following their performance of "Amazing Grace" on The Kelly Clarkson Show.

That's Christmas to Me, A Pentatonix Christmas and The Best of Pentatonix Christmas all moved up following PTX's performance on NBC's Christmas in Rockefeller Center last Wednesday (12/2).

Look for seasonal dominance to continue for PTX as they line up more big looks, including an appearance on The Kelly Clarkson Show this week.

Get into the holiday spirit below.
