Inspired by an Instructable project
https://www.instructables.com/id/LED-VU-Meter-With-Arduino-UNO
Started the project with Arduino Uno.
Modified an audio mic preamplifier from Amazon to condition the output from the laptop music source
Ran the output from this to A0 on the Arduino
Split the signal out to an external speaker
Used digital outputs listed in the sketch to power the LED indicators
Used pins 10 to 12 as AnalogWrite pin to provide the power to the solid state relays.
Used a dremel to separate the power to the hot side of the two power outlets

Sound Reactive Christmas lights on Archive.org
Edit:
Here is the song I meant to add, to see if it matches my video of the lights.
It is the Trans Siberian Orchestra, Carol of the Bells.
