Selling digital art in bulk through prepaid URLs

Suppose a major donor anywhere in the world could sponsor tens of thousands (or any number) of copies of a song, video, or any other digital "content"--letting tens of thousands of people in social networks just click to download free, with no registration ever, instantly paying the artists or a cause by the act of free downloading itself. And each sponsor can deliver a message to the thousands of anonymous end users who download from his or her contribution. We show how independent artists could market globally at no expense if people care about their work--offering an alternative to corporate monoculture. Or they could donate their digital art to an organization that sells it this way to raise funds.
