Came across this, could only get one of the houses in the shot. There are two adjacent houses that are both synched with the music. They have signs in front saying "tune to 107.1" and then both houses match up with the music playing. It's not just one song, it's multiple songs and shows they have on display.
You can't tell from my video, but in some of the windows there are projections of videos or holograms or something of Santa and Mrs. Claus moving around as well.
