Interesting to note that Bruce Lehman, who as former commissioner of patents and trademarks architected the DMCA, now says we're entering a "post-copyright" era. He believes that much of music will inevitably be free to consumers, subsidized by other things. Here's an excerpt from the TechDirt coverage:
He describes the basis for what he, and others, were trying to do with the DMCA. That is, he earnestly believed that such a law was needed to create the framework for economic benefit from an information economy -- and like plenty of others, he felt that the need to do so was to create artificial scarcity to create the right incentives. However, it's turned out that he wasn't just wrong -- but disastrously so.
He recognizes that other business models will have to come into play, and many of them sound like the business models that are already starting to show up. He points out that plenty of other industries need music, and will pay for its creation -- suggesting, for example, that companies like XM and Sirius might "commission" songs. He notes that even the record labels are realizing that the money isn't coming from the music directly, but from merchandise and concerts and are negotiating new contracts to make sure they're included in the profits from those non-music sales.
Or, as I've put it before, "give away the music and sell the show".
