Navidrome on docker replaced my recent Airsonic setup.
Navidrome is an excellent replacement for the recently defunct Airsonic.
After reading about the end of Airsonic development by the maintainer I decided to move my music collection over to Navidrome and I couldn't be happier with the result.
The whole process took just a few minutes, since organizing the actual music folders is the most time-consuming part, and I had that part covered with my recent Airsonic setup.
If you use docker-compose to spin up your servers all you have to do is copy the suggested YAML file to your docker folder and create 2 new folders, data and music, to a location in your home directory, copy over your music collection, and you're pretty much done. You then docker-compose up -d and enjoy the melodies.
Navidrome appears to be snappier than Airsonic, works with substreamer Android app and is compatible with all Subsonic related apps.
