Music desktop app loses songs, playlists, and other anomalies

The desktop Music app (1.4.6.32) is still not working properly – several times I have created a playlist and I see it in Music, I have songs in it, but later it just disappears.

Other times I have a CD in an external reader/burner and it shows up in the Music app twice, even though there is no second volume on the CD, just music. If I eject one of them, the other ones still shows up as being there.

At one point last week, when my iPhone was connected by a cable to my Mac Studio, I checked the box in it’s finder window to “show this phone when on Wi-Fi”. Then I ejected the phone and disconnected the cable. Later when I thought that might be causing problems, I unchecked the box, ejected the phone, and yet afterwards, I see the phone is listed in the sidebar has connected. When I go back into Music, and click on sync settings to open the phone window, I see that that box has rechecked itself! And once again, I unchecked the box close the window, when I reopen it, I see that it’s rechecked itself yet again.

Most troubling, the issue of hundreds of songs disappearing from the Music app continues – I’m still slowly finding and re-adding some of the hundreds of songs that I noticed had disappeared a few months ago, but exist on the computer in the Music folder, which the Music app has lost track of.

And now, the problem persists– in the last three weeks, I ripped six CDs, including one just now, but looking for all those songs in my Library in the app, I see only two (discs worth) of them- one I did about three weeks ago, and the one I just did a few minutes ago, but all the other ones in the middle have totally disappeared from the music app, even though I see the songs in my music folder. This is really beyond frustrating – I never had this problem using iTunes, but ever since I have had to use the Music app when I got this new Mac studio, it just does not work correctly.

I have, of course, restarted Music many, many times, as well as restarting the computer several times in the past few days, but it does not seem to help.

Is there a way to just reinstall the Music app in case it is damaged somehow? I cannot update the OS to the latest version right now, as I have a software program that I use that will not run under Sequoia.
