Music.app messed up the data of my entire music library — help!
The Music.app (v1.0.4.104) application that replaced iTunes on my iMac has gone totally berserk. Suddenly, the artist name, album title and genre of all 4,316 songs (from more than 350 albums, mostly transferred from my CDs) are the same. Has anyone out there encountered this before? I don't know what happened, but any ideas of how I can get everything back to the way it was will be most appreciated. Needless to say, I would rather not have to manually correct all this data album by album. As bloated and problematic as it could sometimes be, even iTunes never did anything like this. My Mac is running Catalina (v10.15.4). Thank you.
