I think the RIAA p2p win is going to be looked back on as a pyrrhic victory in the end. The artists realize that the rhetoric and reality don't meet; the money all goes to the niddlemen. I expect to see more things like Radiohead's announcement - which is what Nine Inch Nails just did:
Hear that? It's the RIAA quaking in their diamond-coated boots as yet another A-list band gives labels the finger: Pretty hate machine Trent Reznor announced today that "as of right now Nine Inch Nails is a totally free agent, free of any recording contract with any label." Instead of futzing through the hapless middleman of an inept label, Trent's promising "a direct relationship with the audience as I see fit and appropriate," so we can expect more experiments in direct distribution and promotion, probably culminating in an album release not unlike Radiohead's In Rainbows.
The RIAA has been so intent on shutting down digital distribution that they haven't noticed what's been made clear: their disdain for their customers and their artists.
