How do I restore my thousands of songs collection from a backup?
I have thousands of songs and other music from many sources backed up on a non-Apple cloud service. I had to wipe my Mac HD and restore macOS 10.15 from the Recovery partition to resolve multiple problems. I then reinstalled all non-Apple software, and recovered Documents and Desktop from iCloud. I do not subscribe to Apple Music, but have recovered both iTunes and Music directories from the cloud backup.
How do I import these successfully?
