This POWERFUL Version Of A Christmas Classic Is Giving Everyone Chills.

Pentatonix has been killing the a cappella game since they blew up on YouTube awhile ago, and this rendition of Joy To The World will help skeptics understand why.

With Christmas just around the corner, the five-person group released this harmonious number to celebrate the holiday season. The song has debuted at number one (the first in a cappella group history), and is part of their new album That's Christmas To Me. Watch their performance of the song below -- If this doesn't get you into the holiday spirit, nothing can.

Here's another song that will get you in the Christmas spirit.
