I love the old traditional Christmas Hymns. Silent Night, Oh Holy Night, etc... if done tastefully. I don't like them being over-produced and butchered beyond recognition.
I despise however, the same 10 songs that you hear all season long: Jingle Bell Rock, Have a Holly Jolly Christmas, All I Want for Christmas is You, It's Beginning to Look a Lot Like Christmas, Rockin' Around the Christmas Tree, Feliz Navidad, etc... I've heard those enough to last me for the rest of my life.
I like Christmas though.
