A relatively new Mac Pro user here in need of direction regarding iCloud storage. I have downloaded a lot of music to Mac Pro and synced with my iPod, 6th gen. How do I get this backed up on the cloud? I have looked through various areas, and even on the cloud icon on my mac, and there is no music there, or even the ability to "check" music to be backed up. It is probably real simple, but I seem to be missing the mark here. Thx
