This is awesome. Is it too much to ask for a music library aswell? I have a headless plexamp instance that would be amazing to control like this. I have tried to edit your yaml file, I managed to make it work with just the track title, but cannot make it to work when I want to add an artist aswell (there may be the same track title with multiple artists)

Hey I came here looking for a way to do music also!
