Family Sharing is an awesome feature in Apple Music; it not only allows the organizer share wonderful content but also gives a family an opportunity to save some bucks while forming a bond. As a family organizer, you can share calendars, photos, movies, TV and music with other members in your family.
Before Family Sharing facility, families had to do with one Apple ID for all content purchase; with Family Sharing plan, six members of a family can listen to music concurrently.
Before you sign up for an Apple Music family plan, ensure that any of your family member has not signed up for a free trial of Apple Music. You need to wait until your family member's free trial is terminated after three months.
