How dare you. I love Christmas music. In part because I can play it at work at a low volume on speakers and not get any complaints because well it helps with the atmosphere. Better then awkward silence.
Still if you're into punk and alternative theres a lot of great Christmas music.
Smashing Pumpkins probably has the most popular Christmas song that isn't traditional or pop.
Some others I can think of:
Marvelous 3 - Merry Christmas
No Doubt - Oi to the World
AKA - Christmas in Hollis
Eve 6 - First Noel
