Pentatonix has planned to run chills in everyone spine and thus surfaced up with the perfect rendition of the song “Mary Did You Know.” To hold up the spirit of Christmas, the group had made the perfect arrangements for the beautiful song. It holds the true Christmas spirit by presenting the song in the unique a cappella style. However, Mark Lowry originally composed this song in the year 1984. From then the song had gone through many remixes and remade. Lots of Artists have tried their hands on this song. But none of them succeeded in presenting the song the way Pentatonix did.
