Cannot join the family plan for Apple Music

Hi madina56

welcome to the Apple (user-to-user) Community:

Re: "Cannot join the family plan for Apple Music"

Wondering what is stopping you.

It is unclear whether you want to subscribe to Apple Music Family:

How to: Get an Apple Music family subscription - Apple Support

or

whether you wish to be included in an existing family Apple Music Family subscription.

Eg: You may need to ask the family organizer to add you to the Apple Music Family subscription:

How to: Add a family member to your shared subscriptions - Apple Support

or

Whether you are already a part of an Family Apple Music subscription, but have not started using it yet.

Seems everyone gets their own Library to which they add the music they want in theirLibrary.

What to do: If you can't find your family's shared content - Apple Support

and

How to download apps and content that your family members purchased - Apple Support
