I don't want to give out the name of my publisher (nor would they want me to), but I can say that a few years ago, they picked up an original X-mas song I co-wrote. It's been placed in two movies (direct to video) and one compilation CD. We get periodic checks for $40-$100
The publisher told us, good X-mas songs are indeed in demand. You're too late to get placed for this season, but perhaps you can get published for future seasons.
