"Santa Baby" - by anybody, especially Madonna
"Silent Night" - Stevie Nicks' version. It's just wrong.
"Christmas Shoes" - This one doesn't make my ears bleed, but it is so freaking sad and depressing, I can't listen to it without crying. Especially dangerous when driving.
But, I DO LOVE "Grownup Christmas List". I think Kelly Clarkson's is the best version.
Oh, and anything by Nat King Cole.
I forgot about the Christmas Shoes song, that one is horrendous. If mama's dead, she doesn't need new shoes! The undertaker doesn't give a hoot what she looks like!
