This is a fascinating article, well written and such food for thought. I encourage you to read the whole article and watch all the clips.

While I was watching, I wondered ... if I were there, would I be one of the passers-by? Or would I have stopped to listen and throw in a few bucks for the pleasure? I listened to the pieces on Rhapsody, and they suit my preferences so precisely that I have a hard time thinking I would not have stopped to listen ... but who can say what they would do if they were on their way to work, late perhaps?
Makes you wonder if this is what humans look like to God when He sends beauty and blessings into their lives ... The most fascinating part was the part about kids. We have so much to learn from them.
Enjoy.
