I have 49 gb of music and at the moment i just sync it between my devices with syncthing. But i think it will be better if i stream it, as the storage on my phone is limited.
Which streaming server do you recommend?
I saw nextcloud music, but i have the feeling it’s half backed and it will just clog my nextcloud install. Or supysonic? Ampache?
I’ve used ampache in the past, but now jellyfin since I’m using it for other media as well
I also have a jellyfin server but last time i tried it (2 years ago) it didn’t seem optimized for audio libraries - using it only for video
not optimized in what way?
If you mean the official phone app, consider one of the third party music-only apps like finamp.
