What's the main music in "Christmas Canon" by Trans-Siberian Orchestra?

Search: transsiberian orchestra christmas canon

Why: Have y'all been listening to KOST 103.5 ("love songs on the coast") since the day after Halloween? Because it's been all Christmas music all the time. The little kids choir version of this came on tonight. I know that music, but I feel like I've heard it played in TV weddings. Is it a Christmas song? I don't know.
