You listed several companies who are competing in the online content market, but I couldn't find any of them who are utilising the blockchain technology and has their cryptocurrency traded on any exchange. I believe that's the difference between Moozicore and her competitors.
You’re right. These are big companies, and they are very popular in the music sharing industry. Yes they don’t have blockchain tech and that’s just one. They also don’t use cryptocurrency for paymensts, which means, users would need to share credit card/ personal information whenever they want to pay for a song.
