What options are there for artists to market their Music in exchange for Bitcoin? How would an artist be able to directly sell his work to his fans?
Regarding this question, its probably worthwhile to check out Bittunes. The company was started in May 2013 with the mission to enable the monetization of file sharing with Bitcoin. The significance of this is that it is not about just using Bitcoin as a way to buy music, but actually incentivising buys (fans) to serve as a new kind of distribution channel for music. ~ In other words, its an 'earning platform' for both artists and fans. It is early days for the system, with many aspects still to roll out. see: www.bittunes.com and www.bittunes.org for more detail.
Liberty Music Store is a place to buy and sell music with Bitcoin. It is geared towards simple user experience. The artist can keep 100%.
