Indeed I have Funkwhale on the radar, but tbh I don't have a strong use case for streaming at home. Was thinking about putting it on my rPi -- but in the end it's even easier to just stream from my iPhone through Bluetooth (or a good old jack).
My priority is to build a clean library with beets, transcode it in mp3 and feed it to iTunes, to have it on my iPhone & iPod.
Honestly, the Plex app is very decent for music libraries these days. Except for oddball VA releases and obscure mixtapes I find Plex to often be terrific at library management.
Second about this. I thought Plex would be overkill at first, but Plex is fantastic for streaming personal music library over internet (especially with Plexamp). One of its best feature IMO is you can make it automatically transcode music to Opus when streaming over cellular or download them locally as-is, saving all headaches of syncing to iDevices.
I've avoided using it because of concerns about library size. I want to move off of iTunes (launch a VM just for this) but nothing else seems to really handle managing a library. Currently trying out Airsonic but it is kind of slow and I can't edit tags with it.
I run all songs / albums through MusicBrainz Picard before putting them in the music directory structure so they're fully tagged. It only misses some of the more local / esoteric stuff I've got.
ive been looking into similar things like jellyfin, mopidy etc for a long time, but i find syncthing to be a lot easier to get my head around and i can use whatever audio player on each app or platform. as long as it can play m3u playlists then im good to go.
only downside is that if you have a really large music library you will have to use syncignore filters to stop some things syncing to devices that don't have enough space.
