I got a new iPhone 6S Plus a few weeks back and have only purchased about 10 songs since. Prior to this I had purchased about 100 songs. When I go into the iTunes store and go to more, purchased, music...it shows under all the 10 songs I've purchased since getting this phone. Under not on this iPhone it says "You do not have any purchased music available to download". Where did my music go and how can I get it back?
