While P2P filesharers locked in an ongoing PR battle against the RIAA are making much of the finding that they are among the heaviest CD buyers in the market, it doesn’t follow that downloading boosts sales of recordings. It strikes me that there’s an easy rejoinder from the music industry. ‘Of course you buy alot, we know you’re interested in music, duh, but you don’t buy as much as you used to or as much as you would if you couldn’t download,’ they might say. Music swappers are more credible, IMHO, when they justify what they’re doing by anti-profit (the record industry appropriates the fruits of artists’ labor; information wants to be free, the rapacious pricing policy of the industry is what is responsible for declining music sales, not us, etc.) rather than disingenuous pro-profit arguments, whatever you think of the merits of the arguments.
