Vouch, this app looks amazing and a desktop app will just elevate it. I’ve been looking for some good music players but all of them have slow updates, are buggy or just are very old looking.
I was using upnp/dlna before moving to symfonium. Emby has dlna support.
There are a bunch of clients, my best experience was with foobar. Theres even a plugin for internet streaming, but its kind of a pain to set it up.
I still love foobar for windows and im using it mounting my media collection on sshfs. Foobar is great because it is maybe even more customizable than symfonium, so i can get the interface just right.
For linux though (my notebook), there are a bunch of apps. My best experience was with strawberry. The interface isnt that great, but its less cluttered.
For web access there are a bunch of clients, including feishin, airsonic, and aonsoku, but to me the standard navidrome web interface is fine.
Another option is for Symfonium to provide a (minimal) web UI over local network, similar to how uTorrent does it, which can be accessed by any browser on any machine and basically control Symfonium over network.
Web UI would have a nice library view with album artists/artists/albums/tracks view and a player to stream the music from Symfonium.
