This is the second time I see such.
None of my music on iPhone is listed in music app, nor any other apps relying on stock music app to work.
Before that, I do a sync between my phone and iTunes under Windows.
Such disappearance has no reason and I don't know what it goes on.
All I can do is not to let Windows iTunes touch my iOS devices before iOS 9 goes publicly available.
