My wife is very Christmasy, I'm not. When we drive to her family's for Christmas, she has to listen to Christmas music the whole way. We compromise by adding various...hmmm, "non-traditional" Holiday songs to the rotation, like....
"A Patrick Swayze Christmas" - MST3K
"Christmas at Ground Zero" - Weird Al
"Oh Lutefisk" - Stanley Boreson
"Christmas in the Trenches" - Hank Cramer
"Christmas in the Carribean" - Jimmy Buffet
"O Little Town of Bethlehem" - Bob Rivers (done to the tune of "House of the Rising Sun")
"The Elves Save Christmas Day" - Futurama
"Christmas Tauntons" - Kirsty Dawson
"Christmastime in Hell" - South Park
"Stop the Cavalry" - Corey Singers
"Hogmanay" - Peter Nardini
"Snoopy's Christmas" - The Royal Guardsmen
Ron "Jingle Hell's Bells" Wanttaja
