Why not go a step further and offer future contracts on artists. For $30 I get the rights to every song or creative work that that artist produces over their career and I can use it unrestricted providing I don't violate their copyright. Let the market set the price and it would be a powerful incentive for commercial artists to directly manage their careers instead of relying on labels.
The key here is how MUCH for those perpetual rights? I bet $1 million it isn't $0.99. I've long thought that Apple should offer a "future proof" version of iTunes downloads (Higer bit rates and "loss protection"). They could charge slightly more for these versions... In this sense, Navio's approach is the correct one- however I do not believe reverse engineering Apple's DRM is the way to solve the problem and I don't belive they will be price competitive.
