There's not many because I usually don't like Christmas music...
Christmas Don't Be Late by Alvin and the Chipmunks. This is from my all time favorite Christmas album. I had this on LP and played it to death.
White Christmas by Bing Crosby - No one sings it better.
Rockin' Around the Christmas Tree by Brenda Lee. The only song I never get tired of hearing.
Blue Christmas By Elvis. Not a big fan of The King, but I do love his version of this song.
I'll Be Home For Christmas by Frank Sinatra. It's Frank. Enough said.
Merry Fucking Christmas by Mr. Garrison. Just because.
Snoopy's Christmas The Royal Guardsmen. It's Snoopy. Enough said.
I'm a Lonely Jew at Christmas Kyle from South Park. I died laughing when I first heard this. And who can forget Mr. Hankey the Christmas Poo?
Christmas at Ground Zero by Weird Al. Christmas isn't Christmas without this song.
The Night Santa Went Crazy by Weird Al. Another great Weird Al Christmas song.
