It also hurts that Christmas Music tends to be shit. Drummer Boy is the worst song ever written.
Gref, you're not secretly my uncle are you? You two need to get together sometime so you can be curmudgeonly about music together. I don't know that your taste in music is similar at all, but I'm quite certain your disdain for music is perfectly matched.
I love Christmas music myself. This is partly because I try very hard to avoid stores that play that syrupy shit they seem to think will get people in a buying mood. Mostly, though, it's because Christmas music to me means the music you sing with your friends and relatives. Simplicity is key. O Little Town of Bethlahem, Silent Night, Good King Winceslas, The Holly and the Ivy, The Wassail Song, Joy to the World, Lo how a Rose e'er Blooming, Wassail Wassail, O Holy Night...these are wonderful songs as long as you don't schmaltz them up (except for O Holy Night, which you pretty much need to).
