The MusicKit video states that you just enable "MusicKit" in your application identifier and "you're done!" Ok, so I did that, and I'm seeing the following error when trying to run a song query: [DataRequesting] Failed retrieving MusicKit tokens: Error Domain=ICErrorDomain Code=-8200 "Media API Token Service's response was invalid (status code: Unauthorized (401))." UserInfo={NSDebugDescription=Media API Token Service's response was invalid (status code: Unauthorized (401))., NSUnderlyingError=0x6000023a0c60 {Error Domain=AMSErrorDomain Code=301 "Invalid Status Code" UserInfo={NSLocalizedDescription=Invalid Status Code, AMSURL=https://sf-api-token-service.itunes.apple.com/apiToken?REDACTED, AMSStatusCode=401, AMSServerPayload={ status = verificationFailure; }, NSLocalizedFailureReason=The response has an invalid status code}}}. Throwing .developerTokenRequestFailed. Is this just broken on Apple's side? Is there some other magic string that needs to be added to the plist other than NSAppleMusicUsageDescription?

We are afraid that apple will reject the app for sharing the similar functionality with the Apple Music app.
