A weird report from the RIAA from Torrentfreak indicates that most "unpaid acquired" music comes from offline file swapping. I find this really, really hard to believe. But hey, if that means they'll stop trying to take over the internet I'm all for it.
Strangely, it still talks about "acquiring" music, which I have frequently questions even as a concept.
After all, what does it mean to "have" an mp3 file? Does that mean you have it on your hard drive? Or that you *can* have it on your hard drive at will? Or "stream" it from YouTube? You do realize streaming is exactly the same as downloading, right?
