I used Vixen software to sychrolize the music. I also built an FM radio broadcast unit so I don't bother the neighbors and people can enjoy my light show from the comfort of their car. I am on 89.9 FM (a clear channel in my area). It is only a five watt transmitter but with my antenna height, I am getting about 2 miles of clear, stereo music.
Each Friday and Saturday Santa's helper will be giving out candy canes and will be on until midnight on Christmas Eve.
