Dave, I am ashamed. You apparently don't get into that rather masterfully crafted piece of music all of us 80's kids know as, "Do They Know It's Christmas Time?" from Band Aid.

And, to tell the truth, I actually get into the synth and sax line of the Waitresses' "Christmas Wrapping." Too bad the lead singer died of lung cancer. :/

There are some good Christmas songs from the 1980's; it's just that by that time everyone was trying to cover everyone else's stuff, so no one was doing anything really original.
