The reality of art, mass art anyway, is that there is necessarily a mechanism of mass production and is therefore within the realm of discussing the "owning" of the rights of the work. I also don't think that we'll ever see the day that music becomes institutionally digitized and distributed free of charge, but that's neither here nor there.
I do and I think the move towards digitizing has already begun as the music industry shifts to selling mp3s online, probably as a reaction to people simply taking their music for free by download. This process of digitization seems to be inexorably moving forward, we'll see over the next few years what that means. What will be interesting to see is how long people continue to pay for something they can get for free and if that will generally collapse the music "industry" as we know it. A niche community like this will be less effected, but the mainstream will likely see massive changes within the next decade. I disagree with the premise that there need be an "inherent consumerist mechanism of mass production" and that the digital age will lead to the scenario I outlined earlier in some less ideal form.
Anyhow, I'm not interested enough to carry this discussion forward into the detail we're heading so we should probably agree to disagree. I'll look into the work you recommended.
