A cappella group Pentatonix has released a new Christmas album, That's Christmas to Me, and while the album contains mostly traditional songs, their rendition of "Mary, Did You Know?" is as stunning and is as moving as any holiday tune I've ever heard. Many have covered it, including Wynonna & Kenny Rogers, Clay Aiken, Kathy Mattea, and most recently, CeeLo Green, but this is simply something else.

I still find it funny to this day that a funny man, Mark Lowry, co-wrote this song. It's amazing.
