Kicking off Christmas music Season: [OFFICIAL VIDEO] Hallelujah - Pentatonix

I have kicked it off in the past by posting the gold standard classic – Charlie Brown Christmas Music Videos. And yes, personally, I like to include Trans-Siberian Orchestra. What would this year be if I did not include Pentatonix, so I am kicking it off with Hallelujah as performed by Pentatonix.
