I've scoured the Internet for information & called Apple Care, but I trust SH forum members more. Background: I have an iTunes library of imported music (CDs & a handful of iTunes purchases) on a PC, Mac Mini & iPad Pro (77,000+ songs). I have NO music on my iPhone X. Here's what I want to do: I'd like to sign up and try Apple Music on my iPhone X only. I do not want Apple Music touching/corrupting my music library on my other devices (PC, Mac Mini, iPad Pro). I'd like to keep it all separate. Is the key to disable the iCloud Music Library and/or iTunes match features (if that still exists)? Is overwriting music files still an issue in 2018? Can I even do this? Any tips appreciated! Thanks!!!
