I decided to start a business after reading Miles Beckler's book about niches. Additionally, I stumbled on to Nazareth's "Expect No Mercy" video on youtube.com; https://www.youtube.com/watch?v=qsnwgaFg4jE. Great stuff. check it out if you haven't already
The most obvious thing that comes to mind is Kiss Playing "I was Made for Loving You". The song that got me started on this journey in the first place.
