I have 6,000 songs in my iTunes library and signed up for the Apple Music 3-month trial a while back when it was first offered, including iCloud Music Library.
After matching, about 3,000 of them are marked 'Apple Music' in the 'iCloud Status' column.
This is improper, as most of these were ripped from cds I own, and hundreds of them are actual live recordings I made myself (rehearsal recordings; I'm a songwriter).
Obviously, this is a problem on my iOS devices; they play different songs.
But I'm also concerned about what happens if I cancel my subscription. I've read that songs you've added from the Apple Music service will disappear. Obviously, I don't want my own songwriting recordings to disappear, but I worry they might since they are improperly marked 'Apple Music'. I have them backed up in time machine and elsewhere, but it would still be a huge hassle to audit the results, discover what is and isn't deleted, and add them back in.
I guess my question is twofold:
What happens to songs that are improperly marked 'Apple Music' if you cancel your subscription? If I choose to cancel, what is the best way to ensure all my recordings remain?
If I choose to stay subscribed, for songs that are improperly marked 'Apple Music' and should be 'Uploaded' instead, how can this be repaired? (I've been reluctant to pick 'Update iCloud Music Library' because of all the warnings to back up your library first - is this safe in my case?) What is the best way to repair my library?
