I understand that Apple Music will include iTunes Match functionality for uploading and match your library. What I'd like to know is your experience if you are an iTunes Match user AND have started your three month trial of Apple Music. Exactly how does this vary from your normal Music app experience on iOS? I'm concerned that enabling the trial period will throw my library into chaos if it attempts to upload my library again. I've seen reports of duplicates. All I can report is 8.4 screwed with one of my playlists only on iOS; it remained correct on iTunes 12.2. Any light you can shed is appreciated.
