I don't think there's a really great business model here but if I'm going to write about the economics of music, I have to write about Radiohead's democratic pricing model. Basically, fans could pay whatever price they wanted for the album. I hear that they got, on average, 8 bucks. There aren't a lot of bands that could pull this off so I'm not sure this is an emerging trend. Worth thinking about though. Could this work for other industries?
