I have thought about, what if we set up a similar gold system that donated money to the Lemmy software, and the instance owner to help cover costs? I’m sure we’d collectively ruin it though.

I’ve used Plex, Jellyfin, and Navidrome. I’m currently using Navidrome, but Plexamp is a massively better product for discovering/interacting with your library. The sonic analysis really takes it to another level.
