Least: 12 Days of Christmas - Oh how I HATE that song
WTH song: Christmas Shoes - everytime I hear it I think..Jesus is not going to be looking at your mom's shoes when he meets her. Besides she'll have wings and will be floating, she'll have no need for shoes.
I'm an atheist too and absolutely love O Holy Night...I get chilld everytime I hear it...every single time, all versions. I don't think I dislike any Christmas Carols...maybe the one about Old King Wencelas (sp?)
