gonic as the streaming server, Lidarr for library management and some of the downloads, Sonixd/Tempo as desktop/mobile clients.

Works alright for albums (downloads are a pain), probably won’t really work in your case though.

Everything is running on a single-node k8s cluster (because infrastructure-as-code is awesome), but it’s probably overkill for most people. github.com/sibwaf/Infrastructure for reference if you’re interested (/selfhosted/charts - lidarr, gonic)

Shameless self-plug: I’m working on a Subsonic-compatible server which wraps yt-dlp (i.e. allows downloading from YouTube/Bandcamp and then streams it). Seems like it should work for your case of handling single tracks. It’s still very much in progress (very-very slow progress) and really isn’t ready for use, but if anyone is interested in following the project: github.com/sibwaf/Tapesonic
