If you do, i promise i will recommend the usage of your system to everyone, for you will be just perfect :-).
Anyhow, i wish you guys the best of luck, and i hope a lot of artists can get well know and make money thanks to you :-)
Great way of reinventing the music bussines :-) The only thing that keeps your system of being perfect is that for cretive commons licensed artists is imposible to sing with you keeping the license. I would recommend you to inform yourselves about the creative commons, and maybe make the pertinent changes to your system so that artists using them can maintain them.
