Making Donations Social

What would happen if donations were made social?

I've been thinking about a crowdfunding music site based on this principal.

-Artists would post their music for free -Anytime a User downloaded/streamed music it would get tracked on their profile -Users would be able to donate money to an Artist and donations would be tracked on their profile -Users would have the ability to enable/disable advertisements. The revenue from advertisements would count towards Artist donations -Users would be awarded "badges" based on donations -Users would have a direct line of communication with the Artist via some social community -Venues would be able to see which Artists in their area were receiving the most donations and contract the Artists for shows.

There's a sense of "discovering" an artist that I think would be amplified because Users would have a record of who contributed to Artists before they became famous. Users would have more of an impact on which direction the music they like moved in.

It's a really rough brain sketch. Thoughts?
