If you play music in the street as you're walking along, or in your front yard while doing something else, you're not doing it for money and you are not doing it to advance any kind of business venture (such as playing music in stores to put customers in a better mood to buy something), so there is no conceivable valid argument for charging you for anything. Rather impossible when no violation or even potential violation has occurred with those parameters.

If you're talking about street performers, that's covered by other sorts of rules. So it's a bad analogy all around.
