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

Yes, you can enable iCloud Music Library on your iOS devices -and- NOT on your Mac/PC..

....

This is how I had my Apple Music setup initially and it was FANTASTIC!! Especially if you want to share your playlists across all your iOS devices (it's actually required).. at the time, though, I did not notice that having this option enabled will prohibit you from being able to sync your Mac/PC music with your iOS device (which I do sometimes) - this is a TERRIBLE feature .. &btw, I eventually enabled iCloud Music Library on my Desktop/iTunes and my Apple Music experience went from FAN-tastic!!! to MISER-able!!!

....

Does anyone else agree? This is the biggest and BEST advertisement for SPOTIFY! -who wouldn't want to be able to listen and manage their playlists both on the desktop AND mobile? Streaming music service is ALL about the Playlists... But like I've said before, this is Apple's initial/beta/1.0 release... I won't be surprised if they lure some SPOTIFY engineers into their camp to get the upperhand, because at this moment they CLEARLY DO NOT.

....

Thanks to my TERRIBLE EXPERIENCE with iCloud Music Library, I was motivated to renew my Spotify STUDENT Premium subscription.. it had expired and I was holding off on renewing because I was giving Apple Music a test-drive... In the end I'm almost certain I will keep both, but Apple SERIOUSLY needs to fix this iCloud Music Library DISASTER!

....

Thank you!

I doubt very seriously they will be able to fix anyone's library. I personally believe that, if you didn't have a backup, you are totally screwed. I do not believe a magic fix will happen for this one. Are you telling me that you actually believe one day they will have a universal fix for everyone whose library was trashed by this debacle? Dream on.

This is quite a bit more than I'm willing to try at this point. There's got to be an easier way.

No. I am in no way, shape, or form, saying they will be able to fix previously screwed up libraries. I am saying that they will release an update (8.4.1?) that prevents it from happening again so people with in tact libraries dont get them messed up.

I agree wholeheartedly. This should be a lesson to everyone with a serious music collection that we should wait to install iTunes updates until we know how those updates affect existing music libraries, and the discussion forums are one place to get that information. Another way is by Googling a particular iTunes update's reviews. I found a very good article when I first became aware of this problem just by Googling "Apple Music". It told me all about the problems with this latest update and led me to the Apple discussions.

I am afraid to look at my albums but I did notice that iTunes is still losing music I recorded from CDs. ***? My biggest problem is a huge drop in CPU load. It used to run between 95% and 99%. Today it is running between 60% and 75%. Anyone else having this problem?

I'm trying to drag an mp4 file into my Iphone but I cant because it says Icloud Music is enabled.

I tried to do the 7 steps steps that Frank Berzau suggested on friend PC but unfortunately I could not delete any song from the iCloud library. I created new empty library but even after deleting the songs from iCloud - they were always coming back. Yes, playlists can be deleted but not songs, and the iCloud still replacing artwork and some songs that were ripped from CD's.

(All other devices had iCloud Music Library switched off and all songs were deleted on the other devices).

my Apple Music service is working great for both the iTunes Match and streaming aspects of it, the only drawback for me is content being instantly being synced across iTunes and my iPhone 6, so I have to add Apple Music content to force the sync/updates.  Hope this helps for anyone in my shoes now.

I had this happen when I first deleted all songs, they were all coming back. I then tried to delete all songs but the ones I had purchased (sort library by iCloud status so you can easily mark the non-purchased ones only). That made it stick.

iTunes was even smart enough to not create duplicates for the purchased tracks when I imported everything.

I am now finished importing all of my music and have just a few playlists left to import. Everything looks great on all devices, except a few cases where Artwork is missing, but not too many to really complain.

Frank, Tx but it did not work too.

I tried this too - left the purchased ones but all of the songs were coming back all the time. Than I thought to leave it for an hour. Still it did not help. Looks to me like Apple is most probably working on this problem so in the meantime we will not be using the iCloud until real fix will be issued. It just too many issues and every time something else coming with new problems.

Even when I at the beginning left my iCloud on, I counted 81 songs that were on my HDD, but Apple insisted that I have to download them from iCloud and when I did they were DRM. Well I said to myself, I can live with this and added those songs from my HDD again, fixed all the tags... and the next morning I've found another few hundreds with the same problem. That was probably caused because the iCloud takes very long time to actually cross reference all the songs that are in the iTunes.

The more shocking stuff were my own family videos that were also supposedly matched by iCloud!!! and shown as "Download from iCloud".

I mean enough is enough!

And Apple still has nothing to say.

After switching over to Apple Music I was shocked to see that everything worked as expected, no playlist shenanigans, no music lost.

Did you enable the cloud library? Did you use iTunesMatch in the past?

Yes and yes.
