With a few exceptions ("White Christmas", "Deck the Hall", "The Twelve Days"), I dislike secular Christmas (oops, "holiday") music.
"Rockin' Around the Christmas Tree"? Yecch.
I reserve particular odium for "The Little Drummer Boy." Cloyingly sentimental, repetitively oppressive, and this years, seemingly, played everywhere.
Most carols, on the other hand, I like. Grouchy, ain't I?
