It’s not free but it’s awesome and cheap. Setup a WebDAV share and join it using “Mountainduck.io”. It connects to everything like SMB but I find WebDAV’s multichannel is more performant in the long run. Checks notes Win/Mac only sorry.

I’ve read on the internet some people export their Spotify to a YouTube playlist to then pass through Parabolic and enter the result into Navidrome. Maybe as a feature you could add a Spotify to YT playlist creator somehow.
