The biggest thing I fear about music is that it is emotional. People want to be in a band and will work for less then minimum wage while living out of a van so they can maybe make it big, but really just to play music. Combined with the fact that in the mind of the consumer a song is near worthless means that the money has to either come from selling massive quantities, aka iTunes and they only break even or something else. And everything that is something else that I have heard of isn't that revolutionary.
