Hello, I'm running Yosemite and iTunes 12.2.25 on my Mac, and and iPhone 5S with iOS 8.4.1 and the newer Apple Music app, connected with a lightning cable. The phone is unlocked. All I'm trying to is copy music from iTunes to my iPhone by dragging and dropping the songs onto my phone (in the left sidebar; it used to be over on the right but - "Hey, let's rewrite iTunes YET AGAIN..." happened). I've tried this several times with no luck. I also tried dragging playlists over to the phone, but no luck. The music in question was created in Garage Band. In the last iTunes this was never a problem. For now, I just can get my music over. This is nuts. Any help would be appreciated. (And yes, I'll go ahead now and update iTunes, though the current set-up SHOULD work...) Thank you.
