If your app connects to Apple Music via its API, it has to respect the service as-is — no modifying playback behavior, blocking Apple Music's own promotional content, or presenting Apple Music content in a way that implies your app, rather than Apple, owns it.
Occasionally triggered by music-utility apps that layer custom UI over Apple Music playback in a way that obscures or reskins Apple's own attribution.
"Your app alters the functionality of Apple Music or fails to give it appropriate attribution, per guideline 4.5.2."
Guideline 4.5.2 covers apps that connect to Apple Music through its API. The service has to be presented as it is: playback behaviour should not be altered, Apple Music's own promotional content should not be blocked and its content should not be shown in a way that suggests the app owns it. Music utilities that restyle playback heavily sometimes cross this line.
Apple provides the Apple Music API so that third-party apps can build on the service, but it still wants the service to look and behave consistently, with proper attribution. Users should know where music comes from, and subscribers should see the same experience, including Apple's own links and promotions, across apps. The rule keeps the integration an extension of the service, not a replacement skin.
Yes, within the terms of the API and the guideline.
Reviewers have access, but developers need appropriate access to build features.
Other services have their own terms, which are separate from this guideline.
