Music stuck while saving library
I recently backed up my external drive (which has my music files (about 82000 songs (802.72 GB)) (the Music Library.musiclibrary is on my internal drive), reformated to AFPS, changed the drive name and then copied my music files back to the external drive. When I go to open Music, it sees all of my songs and playlists, but is not able to find any of the files if I click on any song. when I try to play any of the songs, it tells me that it can't find the song and would I like to locate it. I locate the song and then it asks if I want to locate the other missing files. I click yes to locate the missing files and after about an hour, it tells me that it found all 82k files. Great. I can then play all of these files and everything seems normal.
When I quit Music, it then starts saving the Music library.......but, it just sticks on that - nothing ever happens. I can see that the Music Library.musiclibrary file is modified at the time that I found the missing files. Because it never manages to save and quit, so I do a force quit, restart the computer and then when I open Music, I'm right back where I was - it can't locate the files.
Keep Music Media folder organized is NOT checked
Copy files to Music Media foler when adding to library IS checked
How can I resolve this?
