Subscribe to Apple Music on the web
When you subscribe to Apple Music or Apple One with a family subscription, you can use Family Sharing to share Apple Music with up to five other family members. Your family group members don’t need to do anything—Apple Music is available to them the first time they open music.apple.com after your family subscription begins.
Note: To use Family Sharing, you need an Apple ID, and you must be part of a family group, either as the organizer or an invited family member. To share Apple Music through Family Sharing, someone in the group must have a family subscription—as opposed to an individual subscription—to Apple Music or Apple One.
If you join a family group that subscribes to Apple Music or Apple One with a family subscription and you already subscribe, your subscription isn’t renewed on your next billing date; instead, you use the group’s subscription. If you join a family group that doesn’t subscribe and you have a family subscription, the group uses your subscription. If neither you nor the family group has a family subscription, you can upgrade your account.
Note: To stop sharing Apple Music with a family group, you can cancel your subscription, leave the family group, or (if you’re the family group organizer) stop using Family Sharing.
