Running iOS 8.3 and have about 1,300+ songs that were all downloaded to my iPhone 6. Literally overnight ALL songs on my iPhone were ripped out of the device and now all songs show the cloud download symbol? Why did this happen without me doing anything whatsoever? Very annoying that I now have to go and re-download all 1,300+ songs back to the device. I checked under "Usage" and indeed no Music is taking up any space on the phone any longer. What gives? Forgot to mention I have the highest GB iPhone6, whatever size that is, so I should have plenty of space.
