Hey all, this is Simon, one of the devs from Mirlo. Just want to add this list of alternatives for anyone looking.

Ampwall (really good, kind, and technically savvy folks working on this, highly recommend checking it out)

Bandwagon (focused on decentralization and federation)

Fairplayer (a discovery tool for decentralized music providers, play music from musicians all over the internet, no central db, really good folks)

jam.coop (worker co-op, based in the UK, really good folks)

Subvert (a well heeled multi stakeholder co-operative with a strong marketing department, closed source, centralized).

Mirlo (our project, worker co-op. open source and aiming to be decentralized, of course, I'm biased, but I think we're doing a pretty good job).

LMK if I missed any. Tried to focus on digital purchasing and not streaming.

Edit: feel free to DM me w/ questions or like, hop in our discord.
