@flockofnazguls I'm asking because I'm currently hacking on an, as yet unpublished, selfhosted FOSS app that indexes a library and can then play it to a streamer/renderer on the network, currently only Sonos devices, but designed to be able to support others.

This is in reaction to the recent sonos app disaster, and because Roon lacks a linux remote app.

My needs are fairly simple: fast query by name/title/artist. Ability to create smart playlists to surface eg: least recently played.
