Earlier quoted context omitted.
This sounds naive. The people running the labels are very cynical, and the way they're compensated makes them even more so. They don't have equity. They're motivated by bonuses that come out of this year's revenue. So they're not interested in building stuff. They just want to extract large amounts of money, this year, from whoever they can.
Yes, perhaps thinking the labels changing their ways (or hoping they do) over time is naive. I'll admit that (but I'd like to say optimistic instead). What the music industry needs is a platform where unsigned artists can go to promote their music without the help of the labels. This platform could probably act like a label, but better serve the artists and users. It would have to garner a lot of eyeballs so it could…
They could say "Hey artists not [yet] on a label, join the iTunes Label. We're a great distribution channel, and we'll give you a 70/30 split."
OK so it's a bit far-fetched, and it really depends on what iTunes-as-a-label would provide (but with GarageBand/Logic/CuBase who needs tons of financing?). Really the only thing iTunes doesn't have a great story for would be touring (but even then, what better way to sell concert tickets than through iTunes/Ping?).
