How can I transfer my Music app library to another profile?

Upgraded my computer and used Migration Assistant. Music App migrated perfectly, except that the music is now in an external SSD instead of the main HD. Pointed Music to the files and voila it worked like magic.

However...for reasons not relevant here the main Admin profile (me) was not fully usable, so I created a second Admin profile and have been slowly getting it up to speed (since I had to do everything manually).

Music App however is stumping me. I pointed the app to the media folder on the external SSD, but Music still comes up empty. I then copied the library files over from the initial user profile...still nothing.

How do I manually migrate the Music App config (data, library, etc) from one user to another? I have carefully curated my library over years of collecting and can't stand the thought of starting over...

Help please?
