iCloud Music Library - Cleaning it up
What actually happens if I choose to 'reset iCloud music library'?
Will I lose all files I've uploaded?
Will I lose my purchases?
Will I lose downloads from Apple Music?
Does it treat protected files differently from unprotected ones?
These are the sort of queries to which I need answers.
Why do I want to know? - I have a large library and because of crashes and re-installs and imports and being an idiot, somehow I have many duplicates. Sometimes when I've deleted a duplicate and left only a single copy of a track, when I've tried to play it I've been told it couldn't be found. As it played previously I can only assume that somehow one of the duplicates was recognised and one not ... or something of that sort.
So, in short, I want to clean up my library but not lose anything.
I'd appreciate any help.
