@RobertaFidora #LibreFM kind of laid the foundations for something like that. (I can't recall whether they switched to the #PumpIO protocol or not). These days, I can imagine something like the #Maloja servr, but using the #ActivityPub protocol. Of course, we'd get federated instances, so no-one will be able to get all the data (good riddance, Top10 lists). It could be interesting.
