If you like to watch Christmas Lights synchronized to Christmas Music you may want to stop by 2545 Fussell Way. I recommend you listen to the music on FM Frequency 97.7. I have outdoor speakers but keep them relatively low so as not to disturb my neighbors. The FM is low power and good for about 50 yards from the house. Below is a sample. My neighbors have some nifty lights as well.
Here's a link to a sample:
