Putting music signal into the Analog Input of an Arduino can be pretty boring. That is, unless you use a totally awesome chip like the MSGEQ7. This  simple Spectrum Analyzer driven with an Arduino only takes a handful of parts.  I used these incredibly awesome protoboards from Adafruit for the first time.   The protoboard alone gives a fit and finish even before it starts!
