The CD will die before vinyl. Some say this is strange or even perverse. But it is perfectly well explicable. As a digital medium it offers no more than downloads, streams, rips and all the rest. But it costs about 20x more on average. No brainer.
Non fungible tokens are a very new development. I wonder if performers could sell their music for more than they are getting for downloads and streams? They could make small changes in the performance by digital means that would make each download unique and identifiable by a reference code and logged into a bitchain. They would sell each one as an NFT with all the rights attaching.
