I use Navidrome with play:Sub (paid) or Amperfy (free as in beer) on iOS. I also use the Volusonic plugin with Volumio to play music throughout the house. All my music is curated using MusicBrainz Picard and the files are mounted read-only for Navidrome.
I looked at Roon briefly, and I know many people like it, but I can’t justify the cost. Plex and I don’t get along; pretty sure it’s operator error and/or grumpiness. Jellyfin looks promising, but I ran into challenges with it as well. I think if you’re just hosting music, then Navidrome is fine. If you think you might expand to series or films, something like Plex or Jellyfin could be better long term.
I first recall him trying to shoulder surf Linux’s popularity not long after the XFree86 project switched to a new license that included an acknowledgement clause, so around 2004/2005. I still chuckle when I see that he wants me to call it GNU/Linux, but he has a shit hemorrhage because XFree86 added a license clause requiring similar labeling. He’s made more than his share of contributions, but he takes pedantry to a whole new level.
