The unofficial open source Apple Music web app | Musish
"The unofficial open source Apple Music web app. Github
Built with React and Apple's MusicKit JS while utilizing the official Apple Music API. Contains some serverless functions deployed with AWS Lambda to speed up specific functionalities."
I've been using this web app for a week now, and it's excellent and promising. Gives us hope Apple will release something soon, or at the very least pick up these developers and get a head start.
