The API we were thinking about was simple stuff about transport controls and basic stack of what data we have, for list based navigation
A third party music service API would not work, as to get the magic we do with TIDAL, we needed their entire db backend delivered daily. They were the only service to give this to us, and we’ve asked Spotify, Deezer, Rara, Rhapsody, Qobuz, and many others. This is why most players service integration feels like a bolt on and Roon’s seamlessly integrates TIDAL with your library.
