Christmas Songs

So, what's your favorite Christmas song?
Sure there are the traditional songs but there are new ones to choose from each year. Here are my 6 favorites (at least for this year and in no specific order):

1. We Burned The Christmas Tree - Chaston & Groditski
2. White Trash Christmas - Lurlene the Trailer Court Queen
3. I Believe in Father Christmas - Emerson, Lake & Palmer
4. I Am Santa Claus - Bob Rivers
5. Posada - Santana
6. Mr. Hankey the Christmas Poo - South Park
   

Feel free to comment and list your favorites.
