It would be really interesting if there was a record showing how many recipients of the downloaded material then went on to purchase CDs, showing exactly how much revenue the publishing companies made from Tenenbaum's promotion of their products.

I don't know how many people like to have the physical copy with sleeve notes etc. Maybe not a lot. Maybe most users of downloaded music, only want portable music. I know I prefer the CD played on a good quality hifi, when I can get it (most evenings and weekends). And even though I have music I ripped from CDs put on a portable device, I still prefer to take the CDs into work and listen on my PC rather than the portable device. Don't know why.

I also don't mind paying for legitimate downloads, though I would prefer that most of the money went directly to the artist and not the producer or online store.

In an ideal world art and it's production would be free. As it is not people have to be paid. Publishing companies have production employees who have to be paid too. It is not just some fat cat at the top raking it all in.
