Iphone 5c won't play music without internet connection
I have the latest version of software on my iphone 5c and also on itunes. I have downloaded songs to put on my phone but they will only play when I have an internet connection. This has happened ever since I got apple music but only happens to songs i have put on my phone since then. Some of the songs I want to play aren't even on apple music so I know it can't be because of that. Please help, it is driving me crazy.
iPhone 5c, iOS 8.4
