Lost my navigation for multiple album art in Music 1.0.6.10 Catalina 10.15.7 Late 2012 iMac 27"

Bit of an Update. I found the post on "Retroactive" and used it to install iTunes 12.9.5.5 onto Catalina 10.15.7 (Late 2012 iMac 27). Once the iTunes was installed I changed the location of the iTunes Library to an external hard drive (my Music Library is ~2Tb so could not fit on my local drive). Once the library was relocated I used the File-Add to Library and pointed to the Music directory containing my Music files in my local hard drive. It then chugged away for 36 hours or so and imported all of my ripped mp4 files and artwork into iTunes. Using iTunes I can now navigate through my album art. Enthused that I now had an independent working backup, I called Apple help to see how to un-install Music and then re-install it to see if I could solve the original problem. In short the answer was no. When you use Finder in Catalina and locate in your application file the Music App, right click, you will find it cannot be moved to trash or deleted, it is part of the OS and protected. Moving through the various apps you can continue right clicking to find what apps are considered "core" and what apps can be trashed. If you try to use the App store the only option is for the subscription service version of Music. The long and short of it is until there is a new version of Music bundled up in a revision to Catalina, I am stuck. The plus side is that iTunes seems to be a better app than Music for my use of viewing and playing music.
