This has been gone over before, but I'll chime in again...
Guys, a lot of bands are selling full-resolution albums online. Including
my band, BACKMASK - we offer both FLAC and Apple Lossless in addition to regular mp3.
CDs are dead and if bands and labels don't start getting creative with new business models, the massive sales plummet, and the perception of music as a dying industry will persist. Sure, none of us here like having our music stolen, and most of us here probably don't steal music (or we at least buy the leaked albums we download after they come out, etc.), but we're the minority and nothing is going to change that. Piracy is a faceless crime and it can't be enforced without turning the USA or any other country that attempts enforcement into a police state. Advertising is definitely something that can work and there are a lot of ways in which that itself can be done - from obnoxious audio ads to simple banner ads, or more blended approaches.
I don't know if we're going to see a single business model skyrocket above the rest for a few years. The best thing labels and bands can do is experiment and
fail fast. That is - test new business models, if they fail, kill them quickly and analyze the pros/cons of that failing model. If they succeed, continue to evolve and iterate. The quickest path to permanent failure is to try to force the old model onto the new context. The labels that cling on to the old model for dear life and try to sue and lobby to save it are going to die off and get bought out for pennies on the dollar, most likely by technology companies.
