Apple Music in iOS 9
The iOS 9 release date this fall will include Apple Music on all the same devices. We also know that a new iOS 9 beta next week will include access to Apple Music in the iOS 9 betas.
We know that this is the case for the developer beta, which will reach iOS 9 beta 3 next week with the release, and it will likely time up with a public iOS 9 beta.
Apple confirmed that a public iOS 9 beta is coming in July, and the timing of Apple Music, with a new smarter Siri, makes a perfect time to test out the new version of iPhone and iPad software on real world devices.
