Funny thing about this house is that it is in my area. The guy is an electrical engineer, and rather than broadcast the music over a loudspeaker and annoy the neighbors, he broadcast it on 96.9.
So neighbors only saw blinking lights, and couldn't hear the synchronized music unless they tuned in. It's hard to see in the videos but the middle portion of the house says "Happy Holidays".
Also, the news just stated that his light display has been shutdown indefinitely.
