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

I had the same problem with wrong album artwork being displayed and my playlists were duplicated. I simply turned off iCloud and used my backup to restore. Not sure if I'll use Apple Music again because the setup time is ridiculously long and I really don't need my music in the cloud since I've got a 128gb iphone. I was super pumped about the service but now I'm pretty much over it. Disappointing..

thanks for all the info on this post. wondering what to do here. I turned on apple music/icloud music on my iphone and ipad. then last night updated itunes and it was loading all night. this morning I find everything a mess, but only in music app on devices, my itunes library on my mac seems fine. on my devices it took my hundreds of rare and live tracks and replaced them with the released studio versions, or left them blank. as with everyone else, my artwork is just a mess. I have never used itunes match. So my question is, since my itunes library, over 20K songs and proper artwork etc is fine, what should I do? I'm afraid if I turn off icloud music it will mess it up. Yay or Nay? I just want this apple music crap gone. It is not finished, ready for release nor is it for true music affecionados. I am going back to Google Play, uploading everything and keeping it all there. For those of you on Macs, check out ''radiant player'' it is an awesome google play desktop app for your mac, with different skins and other features. not stuck to google music web player. it is awesome. if someone could tell me next move, how do i get rid of apple music on my devices without screwing up my itunes library, that would be much appreciated. thanks.

This has been happening for over three years with iTunes Match, which is the old name for iCloud Music Library:

iTunes Match Changing My Album Tags/Metadata Without Asking

will my metadata change in iTunes match

iTunes Match vs. Play Counts

According to another user here:

Apple Music/iTunes Replacing My Album Artwork

these are direct quotes from Apple Support:

"When the iCloud Music Library is enabled this will sync the album artwork from iTunes."

"The iCloud Music library places your music into iCloud which does update the album artwork to what appears in the iTunes store."

That would be fine if it stayed in iCloud, but Apple insists on reaching into your personal hard drive and permanently changing your files without your explicit permission. This is just wrong. I hope everyone here gives them feedback (http://www.apple.com/feedback/) and reports this problem far and wide, because just reading the posts here won't motivate Apple to do anything about it.

I have been on the phone 48 Minutes with apple. Guy is nice but clearly has no idea how to resolve this problem. Doesn't even know about all of these new features and I am educating him about it. Waste of my time. They are opening a case and want to research it. Yawn.

I Have this problem too, but interesting fact some or all new files in ~/iTunes/iTunes Media/Apple Music protected

I trying solved this problem with TimeMachine

I meant .itl, sorry

For me it screwed up the Album Art on my iPhone but I've managed to keep it away from my iTunes collection. I am not sure if this is the reason why but I am selecting these options in Store settings on iTunes, this was before enabling iCloud Music/Apple Music.

It just seems to me that Apple has major problems with track alignments in this service. Yesterday I wanted to add Hotel California to my music collection but because I had a live copy of the song with the same title, it wouldn't allow it. Today it's working. Perhaps they're working through this?

If my iTunes files were touched by this, there's no way I'd be using this service.

Can I delete the 'iTunes Library (Corrupt).itl' file after everything is done? Thank you by the way!

You need check all your files and playlists! I change .itl and think what all done, but when I checked I found what many files disappeared((( or moved on ~/iTunes/iTunes Media/Apple Music

My solution it's TimeMACHINE

I found if you go into settings on your iPhone, after updating it and your itunes to the latest software, there is an option to turn off iCloud music, when you press it it changes to an option to have genius on. Anyway, now that it says turn genius on I can synch my music with iTunes properley again.

The exact same problem here, after installing the latest iOS on iPhone and iPad, iTunes 12.2.0 on iMac and start a subscription on iTunes Match. A lot of my 12.000 tracks are messed up with wrong metadata, wrong audio files for artist names, wrong tracks in wrong albums, and the old problem of using random (?) album covers. Most of my Bob Dylan albums are now displayed under a different artist name, as one example. The serious thing is that iTunes is actually renaming and moving the audiofiles in Finder.

I will have a support person from Apple calling me up soon to help. I will let you know how it goes.

Same problem and luckily same solution here too.

Hey, I'm having this problem. I have the correct album art on my Mac, but it's messed up on my phone, every time I try to sync, it just says it is not able to. Did you have this problem?

Hi, thanks for the tip.

I restored a library file taken yesterday morning, but i still have missing music.

What a nightmare - i don't even want to start looking for how many tracks apple has deleted from my library!

What is really disappointing is that Apple in the last year is not the Apple I used to know. The QA is totally down and it is in many areas especially in Mac OS and IOS. It looks to me that they are now rushing products, not doing proper QA and not even fixing many bugs that beta testers are submitting.

It is a pity because I was not used to this from Apple - yes Microsoft Windows and Android were always like this but not Apple. Actually in the last few months Microsoft is getting better and I hope that Apple noticing this.

IMO: Apple should not rush half debugged products just to be in line with others. It is better to be last releasing a product BUT this product is 100% working! The customers will always appreciate this better than messy buggy products that are unusable!

And in regards to Apple Music - even the presentation was very very lame!
