When it comes to Christmas songs, Pentatonix [1] has been killing the game. The a cappella group has slayed everything from "The First Noel" to "Silent Night," [2] and their latest live performance of "God Rest Ye Merry Gentlemen" [3] has totally and completely blown us away. They stopped by Jimmy Kimmel Live on Wednesday, where they belted out the cover from their new holiday album, A Pentatonix Christmas. Although their covers of regular pop songs [4] are usually pretty jaw-dropping, we definitely wouldn't mind if they sang Christmas songs all year round.
