cakasabian - Are you still having this issue? I did too... here's my status....
I purchased a new MacBook Pro in January... out of the box on Catalina... After hours and hours (and to date 4 months), I have gotten to the executive team support. We've recorded the issue... engineering has been able to re-create the issue. They seem to know what the issue is and that it does exist.
The issue as it seems is that changing any metadata and then playing a track will create an issue (sometimes you have to leave the Music app before it explodes your album). It seems that this is also related to missing artwork. I've stopped using my Music app completely because it's wrecking my library.
The good news... they know the issue exists now. The bad news... my executive rep can't commit to when the issue will be resolved. Great experience with them after reaching the executive team and in working to identify the issue, but now it's up to me to wait and see if and when it is resolved. So basically kicked to the curb with no commitment from them to follow up with me unless engineering needs more info. IMO it should've never made it through beta testing.
I'm hopeful that the update will happen in the next iOS update, but there has only been one of those in the four months I've owned the newest laptop. I would urge you to contact the executive team and report the issue -- I emailed Mr. Cook (once) and Mr. Federighi (twice) before being contacted.
To see the issue in action, simply change the name of any album (add an extra word to the end to make it easy to find). Play tracks off the newly named album... exit the app.... wait for awhile... and ta-da your stuff should be jacked up when you enter the app again.
As you can guess, with over 12000 album titles, I'm kinda cranky about the mess!
