I watched the season of The Sing-Off when Home Free won, and was cheering for them all the way. I'm a sucker for a super bass. There are a few different versions of O Holy Night out this year, but this one is my favorite.
But then again, there's the Pentatonix take on O Holy Night, which is done in a completely different style. This is probably my second favorite version of the year. What do you guys think?
