WARNING: iCloud Music Library just destroyed my Mac's iTunes Library

And the bad thing is: I've had that problem already five months ago. iTunes 12.x changed all my data. And I did write a post about it. So they should have known about it.

Been to the Zurich Apple Store, contacted Apple... No help and no interest to help.

That much for listening to the customer - well done, Apple!

i can confirm that this is happening also on windows (i do use both, mac and windows on pc and on the mac). i already wrote before - my music library was completely scrambled. files have been renamed and moved around, album art and metadata was changed, songs have been deleted. so i experienced everything that you can find in this discussion. just going back to an old itl-file was no solution as this does not fix the corrupted files.

well, i hope that everyone who will have the same problem does have a backup of some kind. because in the end this is the only solution that really fixes this mess. of course only if you not forget to turn off the cloud (which in the end cripples apple music to almost being useless).

AS far as i know tuneup 2,5 won't work with itunes 12.2.ıt finds the tracks but i couldn't get it fix it on itunes

don't really know if TuneUp works, or the key you provided, but for all of you that want to try out a cleaning up tool i recommend to take a look at MusicBrainz Picard. It's by far the most complete tool i have come across so far, and it's free. It's a little daunting at first when you take a look at all the options, but it's worth investing a little time in it:

And as always. Create a backup before you touch your library with a tool like this.

I find it staggering that each iOS update seems to cost me a day in time sorting out issues after. This stuff used to 'just work' - I don't want Cloud, I don't want Match, I don't want Radio, I just want a load of music I bought from you to appear as it always has.

with the update to 'Music' on my iPhone, I lost all the ratings info for 1100 purchased tracks. On syncing to iTunes, this caused all those songs to lose their ratings in my iTunes library too (Despite Apple Support saying this shouldn't happen).

Now doing a 10 hour Time Machine back up to return to old version of 'Music'. Will then try to return to old version on iPhone and wait for them to fix this issue in an update.

Have finally learnt my lesson... If Apple offer a software update, don't accept it until you absolutely have to. I understand that the software is complex and some bugs are inevitable, but these days they appear to be every time and quite sizeable issues.

I had the same problem and I just sort it out.

Here is how I did it:

1, Go to Music setting in iPhone, turn off iCloud Music Library;

2, (if your iPhone is connected to Mac/PC), disconnect iPhone, and turn off iTunes on your Mac/PC;

3, Restart iTunes, and connect iPhone with Mac/PC;

4, Drag music to iPhone from iTunes.

I hope it helps.

Cheers!

How can i go back to my old itune. I dont like nothing about this new update or whatever it is.

If, after restore, I end up with a) a working, pre-Apple Music iTunes library on my MacBook, and b) a screwed up Apple Music app on my iPhone (with ratings of 1100 purchased songs missing), should I just be able to connect my iPhone and restore from a pre-Apple Music backup? Or will the screwed up iPhone overwrite my rescued iTunes library (even if I have auto sync off)?

OK. In order to help Apple help us we need to be able to show the root cause. Please start disclosing whether or nor you use cloud and or signed up for Apple music (three months free or not) versus storing everything locally. I've been working with an analyst and this information will help them create a fix as this is impacting tons of users.

Im playing with the idea of reinstalling iTunes and readding my library. Meh?

I am signed up to the three month individual trial. I did have cloud library enabled but have now turned it off. My issue, as far as I can tell, is limited to losing ratings info from all purchased items (which therefore removed them from some playlists, adds them to others).

Jon Sutton,

yes, it will correct your messed up one to be in line with the correct one. You have to make sure iCloud music library is off before resyncing, however. And always make a backup of the library.

this (for the most part) doesn't happen without iCloud music library being enabled, which can only be done with the trial.

Thing is, aside from being time consuming, a complete iPhone restore from backup has other side effects, e.g. I lose all health data because the backups aren't encrypted. So if I get my iTunes library back, what if I just leave my iPhone messed up until they release on iOS 8.4 update which claims to fix iCloud music library issues? Might syncing at that point be a better idea? Or now that it's messed up, is going back in time likely to be the only option?

I am signed up for the trial, iCloud Library is enabled.

My library and it's playlists are exactly the same as before I signed up and turned on. I like Apple Music.

Honestly speaking I believe Apple is well aware of the situation and I hope they are right now working on it. But I have a weird sense that they are just taking their weekends off now as new Apple victims every minute installing and turning icloud sync on watching their libraries being destroyed in front of their very eyes.

The weirdest of all is Apple is not blocking the service or the updates, letting new people getting their libraries destroyed which at least half of them probably don't have any backups at all. Fiasco over fiasco
