Dear Gods, how could someone hear that and *not* stop, if only for a moment? And even if they had no money, not take the time to catch the musician's eye and thank them?

I have busked a bit. I'm not all that good, but a lot of times just haveing someone stop and take a moment to connect with me and share the joy of music was enough. yeah, it won't buy dinner, but it can make a tight belly a bit more bearable.

In the end, it doesn't really matter if you 'understand' the music being performed or not. The one and only way to 'judge' is 'Do you like it?'

Life and the world is filled with music of one sort or another - take a moment to enjoy it and help the universe renew itself.
