How get Mac Music to update its library data based on my folder structure?

I started my shift towards apple products over 17 years ago when I purchased my first iPod (yes the click wheel one). I started by using iTunes software for managing my music library, then I bought my first iPhone then switched to using mac book pro. Now, over all these jumps i moved my library from one computer to another, letting iTunes manage files. Then came Mac Music... My current situation is that I have all my music in the /Users//Music folder but, within this folder they are all over the place. /Users//Music/iTunes/iTunes Media/Music /Users//Music/iTunes/iTunes Media/Music/Music /Users//Music/Music/Media.localized/Music (What does '.localized' mean?) I tried consolidating the library but I can still see many files/folder outside the media folder. I have manually moved the music files to the media folder now but, how do I get Mac Music to change the location of the files, in its library, based on what is on the hard drive?
