@mike yes, I have a bit. It is easily installed with yunohost in fact!
Maybe this is offbase, but it seems to be oriented around decentralized sharing with friends than helping artists & labels get paid for their work and having fans who help support them?
I suspect those features could be added on? I also think there is value in having some centralization & governance so that artists can focus on their work rather than sysadmin? But maybe there could be a recognizable & trusted instance?
