Interesting idea ... the question becomes which comes first: the 'customer' or the 'artist/label' ? In the case of iTunes, Apple had a captive customer base, and the size/credibility to bring the labels on board. Fibo has neither at this point, and I'm not sure a crowdsale gets you there. I'd love for this to work (and to short AAPL along the way) ... hmmm. If I see some momentum I could see myself jumping aboard ...

Also, in your shoes I would take some notes from Augur's crowdsale, and consider selling 'Fibo' coins that grant the right to mine and generate revenue. The crypto community likes to have their interest 'monetized' in the form of some type of fungible coin or token.
