I’ve been using Jellyfin for years, on different hosts. Music has never worked on any of my devices - there’s a bug where you try to play a track and it ignores you and plays the first track off the album instead. You can literally never play anything after that. To be fair, I haven’t tested this in six months, but it was a consistent bug for years before that and I’ve tried every client under the sun. Nowadays I use Jellyfin for video and Navidrome for audio instead and it’s all good.
