I read this comment from another website regarding turning on iCloud Music Library: Your original files will remain untouched. Only if a song can be found in the Apple Music Libary and you download it on another device, the downloaded file will be DRMd. If a song cannot be found in the Apple Music Libary a copy of it will be uploaded to iCloud and if you download it, the downloaded file will be DRM-free. So as long as you don't delete the original files, everything will be fine, also after you have cancelled the membership. (And yes, I tested it myself.) (Thrice.) (With three different songs.) I'm really worried about my original music library. Can someone please confirm if this behaviour is true? I'm really worried what happens once day, if I cancel Apple Music.
