I upgraded my iMac to Catalina, and now I have two music libraries. One is "Apple Music" and one is "Music", both in the user/music/music/media folder, which has two subfolders one called "Apple Music" and one "Music". They appear to contain a ton of the same music/files.
I'm not as Mac fluent as I should be, but I am concerned about having duplicate libraries, or deleting one if they aren't exactly the same. Any ideas why this is, and what I should do? My real concern is wasting a ton of storage space, which I don't want to do, but do want my entire music library stored locally.
