So I've been using Apple Music. Since I play a lot of music in my car, I like to "save offline" on my iPhone, so I HAD to enable iCloud Music Library. Now I have an old Christmas Music song collection on my computer, that I only put on my iPhone around Christmas time. Now it seems like I can't sync it to my phone anymore, because iCloud Music Library is enabled. When I first enabled iCould Music Library, it merged the Apple Music stuff with my existing library. Was this just a one-time thing? Can I now never sync music from iTunes anymore without losing my Apple Music downloads?
