With the transformation of Bitcoin as a payment method, we can apply this model on the net. The fact that the payment is fast, simple and cheap makes it worthwhile in terms of the artist. Distinguish from the street - the artist can reach a much larger audience and revenue potential is many times greater.

I think the very idea of street music is that it is live and you can enjoy it the open air. Try to see the same performance on the computer screen and you will hardly like it. Also you can toss $0.5 in a hat on the street easily but to transfer $0.5 worth of BTC is problematic because you'll have to pay the same amount or even more as a transaction fee. Thus, in my opinion, it wasn't a great business model, but maybe if a street musician will hold a sign "We Accept Bitcoin", it will make some people smile and they will stop for a second to give some money instead of just passing by.
