I think the author ignores the elephant in the room: RIAA being part of the labels share > the artists share - ever! So torrenting a track/disc/anthology monetarily hurts the labels more.
However, it hurts the artists disproportionately more, but this is because artists get a paltry amount anyway. So they get less or none of their $.35, but labels get none of their $15.
My hope for all this is that artists will just empower themselves and use the newer channels of distribution the internet offers. I can't in the least bit, after all their congressional lobbying to restrict the public rights and expand their corrupt initiatives, feel bad - ever - for the RIAA or labels. Everyone knows their fat, lumbering, dinosaurs..
