Q: If i set up a family sharing under my account will my wife still pay for her own music and can i access her purchases

Hey William Wiles, 

Thanks for the question. After reviewing your post, it sounds like you have a question about purchases with Family Sharing. I would recommend that you read this article, it may be able to help you resolve or isolate the issue.

Family Sharing

Once you’ve set up Family Sharing, all the songs, albums, movies, TV shows, books, and apps ever purchased by family members are immediately available to everyone else in the group. And, of course, so are new purchases. 

 

All new iTunes, iBooks, and App Store purchases initiated by family members will be billed to the family organizer’s account.

Thanks for using Apple Support Communities.

Have a nice day,

Mario
