On Tuesday, June 30, 2015, Apple updated their iTunes Store Terms and Conditions just hours ahead of the iTunes Music launch. Anyone downloading apps or app updates from the iTunes Store will have to agree to this, as will anyone installing iOS 8.4, as well.
The big changes are the inclusion of a new section detailing Apple Music, with mention of "iCloud Music Library" that sounds eerily familiar to iTunes Match (though iTunes Match is still listed elsewhere). Apple Music will require iOS 8.4, iTunes 12.2 and Android 4.1. Additionally, Apple now (for good reason) has the right to use your playback information to report to licensors and pay royalties. This covers both the new Apple Music service as well as iTunes Match.
