Oh, a shameless self-plug opportunity. TLDR: I'm making a Subsonic server trying to replicate a somewhat passable self-hosted Spotify/... experience.
My current setup is a Subsonic stack: gonic as a server, Lidarr as a library organizer/downloader (it works natively with Prowlarr BTW) and Sonixd/Tempo as desktop/mobile clients. Frankly, it sucks - no discovery and almost nothing gets auto-downloaded. Even ignoring the crucial discovery part, I got tired of manually downloading albums from Bandcamp - manually tagging, manually feeding files into Lidarr, manually adding metadata to MusicBrainz so Lidarr actually works, ...
So, I've been working on a Subsonic-compatible server for quite a while. The basic idea is:
- regular user libraries are already covered by various Subsonic (and other) servers, no need to reinvent this
- we can, uuuuh, cache stuff from YouTube/Bandcamp/... to stream it via Subsonic API to leverage existing clients
- we can fetch recommendation lists from somewhere else (ListenBrainz/...) and use the existing library or even auto-search YouTube/Bandcamp/... if the track's missing
Well then, what can Tapesonic already do?
- given a YouTube/Bandcamp/maybe-more URL, download it and then two-click import it as a playlist or an album, making it listenable via most Subsonic clients (single-video "mixtapes" with timecoded chapters and playlists are supported)
- combine your "main" library (from probably most other Subsonic servers like gonic/Navidrome/...) with it's own so you don't have to switch servers back and forth
What's broken/not implemented yet?
- acceptable server UI; features are far more important especially considering that the goal is to use the existing clients for almost everything
- seeking in clients; working on a fix for the past few days
- transcoding; not a priority for now
- auto-searching YouTube/Bandcamp/...; not a priority for now
- ListenBrainz playlists; I have "already listened" playlists kinda working in a stash, but those are paused until seeking works; "discovery" will just work after auto-searching gets implemented
No user documentation, half-broken, breaking changes one after another, slow progress - but hey, it doesn't mess with your existing library and already made my life quite easier with Bandcamp albums. A docker image is available - so give it a spin if you want to ~~and then ragequit because it sucks~~
Hey, that's almost what I made Gire for. It doesn't support completely anonymous reads though (requires SSH keys for auth).
