This is brilliant. I've been thinking about making this for a while. If I add a band's email address, would that then be available to other people who listen to the same artist? How would you stop wrongly donating to artists with the same name?
Artists' email addresses aren't shared right now (bc then it would be easy to pollute with wrong addresses).
