The Canadian Record Industry Association (the Canadian version of the RIAA) has released a study in which they conclude that P2P downloaders buy lots of music, and that P2P doesn't particularly harm their industry:
In summary, CRIA's own research now concludes that P2P downloading constitutes less than one-third of the music on downloaders' computers, that P2P users frequently try music on P2P services before they buy, that the largest P2P downloader demographic is also the largest music buying demographic, and that reduced purchasing has little to do with the availability of music on P2P services. I've argued many of these same things, but now you don't have to take my word for it; you can take it from the record labels themselves.Link
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
