Do you have a 3-month family plan for Music?

Hi brainstewn,

Thanks for contacting Apple Support Communities!

We understand that you're interested in sharing an Apple Music trial subscription with your family.

Family sharing does allow you to share subscriptions and purchases, even if the subscriptions are for a trial period. Check out this resource which will show you how to share content with your family via Family Sharing: What is Family Sharing? - Apple Support

"Share Apple subscriptions

Whether it’s music, TV and movies, news, games, or fitness, Apple subscriptions have something for everyone. And with iCloud+, you can share storage and features like iCloud Private Relay, Hide My Email, and HomeKit Secure Video support with your family.

When you use Family Sharing, your whole family can share access to the same Apple subscriptions. With Apple One, you can bundle everything together for one low monthly price. You can also share some other subscriptions that you sign up for in apps from the App Store.

We hope this helps you.

Cheers!
