It shouldn't be too hard to create a blockchain music player. I'm not an expert on this kind of tech but I can imagine the songs added to the chain and a small amount of cryptocurrency will have to paid for each play. The owner of the song then collects the funds, and every user pays for each play which is streamed from the encrypted blockchain and, sure, a third party capture program could steal the feed and then distribute it un-encrypted but the ease of use and extremely low cost should be enough to discourage that from being a real problem. Exciting times ahead for blockchain tech!
