The other day I tried to drag and album from iTunes onto my iPhone but it said to turn off iCloud music first. I thought we could have both synced from iTunes music (in My Music) plus iCloud music at the same time. Also after I turned off iCloud Music and dragged an album onto my phone, that album did not appear in iCloud Music when I switch iCloud Music back on. It didn't appear in my iPhone's Recently Added playlist or anywhere. Even now, that album is in my iTunes but not in the cloud even though I turned it back on.
