Changed apple id email, lost music
I recently changed my apple id email and password. Now, on my iPhone, all my music is gone. I logged out and in on my iPhone using me new apple id, but all my old music is gone. The only music currently on my iPhone are the songs I downloaded after I changed my email. I am traveling on vacation and cannot synch my iPhone to my computer. Is there anyway to get my music back on my iPhone? I don't know why this randomly happened today!
Any help would be greatly appreciated!
iPhone 6, iOS 9.3
