Apple Music has freaked me out because I have a lot of my own recordings - rehearsals, etc. After turning on iCloud sharing, it uploaded most of them, but it says others aren't available, and some of them got matched incorrectly. They say when that happens, to delete them from your source library and then re-add to let Apple match it again, since it apparently gets more accurate over time. I haven't tried that yet since it's a huge project to back up my recordings in a separate location and then re-add (even though I have the library itself backed up). The other thing I can do is cancel my iCloud sharing / match account, but then I'm not sure what happens to my recordings - even though it's my source account, I've heard horror stories about iTunes deleting some recordings on account cancellation if they've been categorized incorrectly. So I've just felt sort of stuck until I find time to do some major surgery.

I have the same issues. Substitute Photos app for Apple music here and I'm in the same hole for that app too. Having just uploaded 75,000 photos for the third time in a year, its getting a little tedious. It's dammed infuriating with music but the inconvenience is nothing compared to the Photos shambles as that collection is large.

You're overthinking it. If you turn off iCloud Music Library, any music you already had on your computer is fine. This means your pre-existing music library will be fine (assuming you didn't delete the music files off of your computer). Yes, there was a bug at one point that could cause it to delete some of your existing music, but it was relatively rare and was fixed shortly after it was discovered.

As for matching, are you adding it from your iPhone, or from your computer? Music matching is a lot more exact if you're adding it from your computer.

That bug must be what I remembered - I missed that it got fixed, all I heard was that Apple was working on it. Thanks for letting me know, I think I might nervously shut it off and revert to manually controlling what songs are on my phone. Do you remember any sources on what it was and when/how it got fixed?

I added them from my laptop - I find the matching pretty lousy, though. Bjork recordings are replaced by acoustic remixes, live-radio performances of songs are replaced by studio recordings, etc. And then of course some of my own songs are replaced by weird recordings I've never heard before. It seems that any time I'm out and about and listen to a playlist for 30-45 minutes, at least 1-2 songs are wrong.

All of these recordings are of course still fine on my laptop itself - I know not to delete those.

I don't really know the details on how it was fixed, but I feel like it was fixed within a week of it being first reported.

As for the matching, I'm not sure what to tell you. To the best of my knowledge, all of the music I have was matched correctly (or uploaded if there was no match). That said, I was originally an iTunes Match subscriber, and it's certainly possible that maybe iTunes Match used stricter matching, though I don't know why that would be because that sounds weird.

In the past Match used stricter matching than Apple Music for no real good reason. They are the same now.
