Apple is rumored to be working on a subscription services bundle called "Apple One," which could see a launch in the near future, according to code found in the Android version of Apple Music by 9to5Google.
Signs of an "Apple One" bundle were found in the 3.4.0 beta of Apple Music for Android, confirming that Apple Music will be one component of the services bundle. From the Android app code:
Your Apple Music subscription will be included in Apple One starting %s. You will not be charged for both subscriptions.
You can manage your Apple One subscription using your iPhone, iPad, Apple TV or Mac.
There is wording that indicates customers who upgrade to Apple One will not be double charged for Apple Music, and that the Apple One subscription will be able to be managed on iPhone, iPad, Apple TV, and Mac.
