The comparisons to open source software never do much to convince me. Many people think that it is a good model and make money through it sure, but I believe commercial software makes more money and that money is easier made (for example money from a sale instead of money from support seems much easier to do and scale).
The digital music space has been improving (iTunes has been DRM free for a while now) and it's hopefully going to get better - probably as more of the old media people retire and the companies enter the control of people who have grown up with digital content. The only way things will move forward is if both sides compromise but the mentality some people have of 'I want it now, I want it in the format I want, and I want it free' doesn't do much to convince music/movie/book companies. It makes them want to lock things down tighter, not open them up.
