I am a die-hard Jellyfin user, but I still haven't found a proper way to index and stream my music library with it. As far as i know, Plex is still better at that.
Navidrome and Airsonic advanced provide a better music experience than jellyfin for me anyway and both are free.
I've recently had really good luck with Finamp on Android at least. With the recent support of time lyrics in Jellyfin and Finamp's redesign I've been using that to stream my Flac audio files. Works quite well with separate collections as well. Though, to this day I still have to force close it more times than I like to get the UI to refresh after closing it. Plexamp was tough to lose when I swapped many years ago, but the third party space has slowly been closing that gap over the years.
