thanks for the comments.
However, I want to point out one more thing: the average Spotify freemium user - meaning 60-70% of all platform users - will not start buying some intermediary token with their hard earned fiat just to tip an artist when they can listen to the artist for free as well.
You gotta be a really big fan of an artist to take that hurdle.
Then, on the other side, I doubt that UBI will be capable of paying every artist. Additionally, it punishes small artists when every artist is paid according to the amount of plays IN RELATION TO all the other artists on the platform.
Plus, for miners there's no or only a very small market, assuming that 60-70% (in the beginning probably more) users will not pay for coins.
I understand that most people don't like ads and those people could still buy a "premium-like", ad-free experience. But you have got to find a way to monetize the "free" users. There's a reason why Soundcloud is on the brink of bankruptcy and Spotify is not.
