Apple Music?
Why am I being charged for music purchases when I have Apple Music
Question marked as
If you have an Apple Music subscription you can still purchase downloads if you wish. But if you only want to download Apple Music tracks for offline listening, you can do so at no charge. Make sure you know the difference:
Add and download music from Apple Music or buy music from the iTunes Store
