So this just happened.. I had my iPhone 6 (9.0.1 jailbreak) connected to my Mac, trying to recover some deleted photos (didn't manage). When I checked my music library this morning, I was shocked to see that the 'last added' songs were form like 3-4 months ago. I have no idea what happened, I never fully understood iTunes, iCloud and all things related and I never used it either. Can someone explain to me how I can get my library back ? I am sure I didn't click on any syncing, that would override my local iPhone data... Thanks!
