They happily let you pay for both even though Apple music includes the functionality. I recently found this out when I moved, and had to escalate at apple support to get them to cancel the remaining 6 months of my itunes match subscription and everything kept working via Apple Music.[0] [0]Because you can't change regions while having an active subscription. Normally you are blocked from doing so but apparently if you use family sharing, the head of the family can change regions and your account will be broken.
