So can we develop a music app and release it?

Greetings @Murat Yasar,

MusicKit can be used to develop music apps in accordance with the App Store Review Guidelines:

4.5.2 Apple Music

(i) MusicKit on iOS lets users play Apple Music and their local music library natively from your apps and games. When a user provides permission to their Apple Music account, your app can create playlists, add songs to their library, and play any of the millions of songs in the Apple Music catalog. Users must initiate the playback of an Apple Music stream and be able to navigate using standard media controls such as “play,” “pause,” and “skip.” Moreover, your app may not require payment or indirectly monetize access to the Apple Music service (e.g. in-app purchase, advertising, requesting user info, etc.). Do not download, upload, or enable sharing of music files sourced from the MusicKit APIs, except as explicitly permitted in MusicKit documentation.

(ii) Using the MusicKit APIs is not a replacement for securing the licenses you might need for a deeper or more complex music integration. For example, if you want your app to play a specific song at a particular moment, or to create audio or video files that can be shared to social media, you’ll need to contact rights-holders directly to get their permission (e.g. synchronization or adaptation rights) and assets. Cover art and other metadata may only be used in connection with music playback or playlists (including App Store screenshots displaying your app’s functionality), and should not be used in any marketing or advertising without getting specific authorization from rights-holders. Make sure to follow the Apple Music Identity Guidelines when integrating Apple Music services in your app.

(iii) Apps that access Apple Music user data, such as playlists and favorites, must clearly disclose this access in the purpose string. Any data collected may not be shared with third parties for any purpose other than supporting or improving the app experience. This data may not be used to identify users or devices, or to target advertising.

Best regards,

Hi.

My app under development currently allows users to play music from their local library. The app will not have in-app purchase or advertising, but will be a paid app (one-off payment). Does this mean that I cannot add Apple Music streaming and must only use the local music library?

Cheers, Ian
