Hello, I am developing an iOS app that uses MusicKit and ApplicationMusicPlayer to create automatic transitions between songs from Apple Music. The app already analyzes tracks using BPM, musical key and danceability, orders them for compatible transitions, and uses MusicPlayer.Transition.crossfade for playback. With the public MusicKit APIs, however, I have reached a limitation. ApplicationMusicPlayer manages the playback queue and crossfade internally. I cannot independently control the outgoing and incoming Apple Music tracks as two decks, which would be required for DJ-style transitions (for example, starting the incoming track while independently controlling the outgoing track, choosing precise mix points, and managing the two playback positions during the overlap). I experimented with MusicPlayer.Queue.Entry startTime and endTime, but changing the end point is not equivalent to having independent deck control and can result in the current track ending before the desired transition. I understand that Apple Music content is protected and that direct access to decoded audio samples may intentionally not be available through the public MusicKit APIs. I am not looking to download, extract, record, or export Apple Music audio. My use case is real-time playback only, for authenticated Apple Music subscribers. My questions are: Is there a public API that allows two Apple Music tracks to be independently controlled and mixed in real time? If not, is there a restricted entitlement, API, or developer program available for DJ/mixing applications? If this capability requires a commercial or technical partnership with Apple Music rather than a public API, is there an official channel through which a developer can request or discuss such access? I am aware that some third-party DJ applications provide real-time mixing with Apple Music, so I would like to understand whether there is an officially supported integration path for other developers, rather than trying to work around the limitations of ApplicationMusicPlayer. Thank you.
