Something went wrong with my iCloud Music Library this morning. I now have a few thousand songs with incorrect metadata.

I have a backup of my Mac's iTunes Music Library, and the backup is correct. When I restore the backup, my library is correct again for a few minutes, until iCloud Music Library syncs and replaces the correct metadata with its incorrect metadata, presumably because iCML sees that its own info is more recent than my backup. ARGH!

NOTES:

The only library I care about is my Mac's iTunes library. I use iCloud Music Library for Apple Music downloads on my Mac, but I've turned it off on all of my other devices (an iPhone and an iPad). I've also deleted all music from my iPhone and iPad in order to make it easier to fix this problem.

How do I force iCloud Music Library to sync its metadata with the correct info in my Mac iTunes Library?

    If the "more recent info" suggestion is really the problem, you could try to (1) disconnect from the internet (2) restore you backup (3) update metadata for all songs (e.g. select all, add a comment, save, then delete the comment) (4) reconnect and see what happens. However, I had similar problems before (only for single songs, though) and I think the meta-data update isn't very reliable - it always stupidly tends to prefer the online info. – Chris Jul 11 '16 at 21:18
  • THANK YOU! Geez, your solution is obvious, and I mean that in the best possible sense, as it should accomplish exactly what I want. And yet, it hadn't occurred to me. If it doesn't work, then it shows the problem is bigger than I thought - though, it shouldn't work since it looks like my backup is correct and iCML is wrong. – 2oh1 Jul 11 '16 at 21:35
  • Shoot! iCloud Music Library is doing crazy things. I added the word "UPDATED" to the comments for every single song. Then I quit iTunes and backed up my iTunes library files. As soon as I turned on wifi again, iCloud Music Library started deleting ratings and sometimes also deleting the UPDATED comment. I can't fathom what's going on here. – 2oh1 Jul 12 '16 at 0:25
  • Could you completely turn off iCloud Music Library and then re-enable (and re-upload) everything? – Chris Jul 12 '16 at 20:11
  • Turning off iCloud Music Library doesn't delete its contents. I've done that before, while trying to solve problems with iCML. The only solution I've found that works is to only use iCML on one device (my Mac). As soon as a second device gets added, iCML seems to lose track of which files are more recent. Inevitably, iCML prioritizes its metadata in the cloud over the metadata in my iTunes library, even when iTunes is more current. I'll change ratings, loves, etc, on songs in iTunes, iCML changes the info back or deletes it. It's maddening. Delete songs? iCML re-adds them. – 2oh1 Jul 12 '16 at 23:38
