I managed most of those horrors by disabling "manage my library"I could go on and on about things Apple Music did that drove me nuts. Just a few…it would upload a CD using the match service. I was lucky if the explicit versions matched to the explicit versions and not clean. This was also a problem with the official iTunes Match service when it came out in 2011 or 2012. What it also did was it would match those songs to the library, and if the song ever disappeared from the AM catalog (if the right ended or for whatever other reason), then it would grey out the song in my library. My own ripped song that they matched!! In my eyes, if a matched song disappears from the catalog, then the computer where the original lives should automatically upload it to the iCloud Music Library to replace it, instead of rendering your own ripped song useless.
Another thing it did was caused me tons of headaches managing metadata. Often times changes I would make wouldn’t sync, or Apple Music in its own would randomly split albums and make it impossible to rejoin them. Even if I could get the computer to rejoin them, they may not show up that way on the other devices.
Another thing is it really didn’t like duplicates of songs in the library. For instance, greatest hits and an album having the same song. Often times the song would disappear out of its main album. Lo and behold, I’d still find it in the greatest hits. So I still had the song, but not in both places. Other times, I wouldn’t even have the greatest hits in my library, and yet it would switch the album version of a song for the greatest hits version. So let’s take Eminem “My Name Is” for example. I have the slim shady LP in my library and do NOT have Curtain Call: The Hits. One day My Name Is disappears from the LP and shows up in my library under Curtain Call. I open curtain call and go figure, My Name Is is the only song in there because I didn’t have Chrtain Call in my library.
All of that type of crap happened all the time. I had a 30k song library. Jay is a lot to constantly manage when so many issues pop up. I just couldn’t deal with it anymore.
At least with my CDs I pretty much manage the library and leave it alone.
I have said it before, what I think Apple should do is redo iCloud music library and how it works in theory. Let it be a hard drive for your music and let it use iCloud storage. I would happily pay for 2TB of iCloud storage to store my whole library on iCloud and upload exact copies. I don’t even need the Apple Music catalog. Songs disappearing at random makes Apple Music not worth it for me. I’d rather just own the music. The problem is getting the music to my phone. Syncing over a cable works fine, but it is Stone Age level. If iML was a hard drive in the sky built into the music app that runs through iCloud, that would solve every complaint I have as long as they built it to sync properly. Knowing Apple, they would probably ruin the syncing somehow though.
That has saved so so so many issues. I have about 10K CDs ripped. I did a backup before I tried iTunes (back in the day) and still maintain a backup out of Music's reach. No - I don't trust it.
