This link unfortunately no longer works

Also as far as I can tell, there is no support for this /recent/played/tracks in MusicKit JS, despite there being support for /recent/played. Very frustrating. Wish they would just release it as a node library instead of having us load a script to use it.

Why not just let us pass a callback/redirect uri, and return the code as a query/url param? That would make user experience a lot better. Currently as it stands, calling MusicKit's authorize() method in iOS 16 Safari and Chrome is broken. The page simply refreshes on Safari or gets caught in a loop of logging into Apple in Chrome.
