This is what happens when I cut down on my music watching activities. How did I miss this group? If it were not for my Wizard of Ahhhs post, I would still be in the dark of this feel good experience.
Pentatonix sound great and this medley is fun to listen too. Now I'm going to go on a Pentatonix (yes, I freaken love acapella darn it) binge on their Youtube page, PTXofficial.
