Semicolon listed the Christmas songs she doesn't like, after reading which Odious gave an excellent demonstration of what he does to people who sing "Jingle Bell Rock". Sometimes he overreacts to things.
I have to say, I really can't think of any Christmas songs I hate. After a while I do get tired of them, but probably the only ones that make me roll my eyes at the opening bars are "Jingle Bells" and "Santa Claus Is Coming To Town". Mostly I just love Christmas. I love shopping for gifts for the people I love, putting up decorations (my Christmas lights are currently shedding a cozy glow from our balconies), baking goodies, attending Advent church services, planning gifts for those in need or choosing a charity, making my own gifts, writing Christmas cards, reading all the delightful Christmas stories and watching our long list of movies... it's a good time of year.
