Massively ironic IMO
This idea may work to establish new artists and help them promote themselves. But the rights management aspect isn't built for the 21st century, it is 100% unfeasible to "sell" digital goods that derive their value from being converted to analogue (so all forms of media). Technology enable the selling of recorded music for a tiny, brief period of history. Technology has quickly made that business impractical.
The real benefit of cryptocurrency to musicians is not adding even more layers of middlemen, it's about removing them. Record labels, distributors, rights owners/publishers; all these parasites will be banished to the annals by musicians (and other artists) using cryptocurrency to gain complete independence to do business on their own. Along with the producers, studio owners, mastering engineers etc that technology has already helped to replace.
