Existing apple music subscriber joining an existing family plan
I've been an individual member of apple music for a few years and have a lot of music downloaded to my devices through this plan. My partner also has a plan and wants to switch to a family plan, and put me on it. How can I do this with no impact on my music library? Don't want to cancel and resubscribe under the family plan, unless 100% certain I won't look the data around liked songs, downloaded songs, playlists, etc.
