FAMILY SHARE QUESTION
I WANT TO USE FAMILY SHARE TO HAVE APPLE MUSIC SUBSCRIPTION ONLY BUT HAVE SEPARATE CARDS FOR PAYMENT OF MOVIE AND APP PURCHASES AND KEEP THOSE PRIVATE.

You can only have one credit card on an account at a time, that will be used for all purchases on that account - and if using family sharing and you're the organiser, any purchases made by other family members will be charged to that credit card unless those members have a balance on their account (if their balance doesn't cover the entire purchase the balance will be charged to the card).
(For future info typing all in capitals is considered shouting, makes posts difficult to read, and may mean that people are less likely to reply.)
