i did the IOS 10 downgrade, and it worked, only problem is my music wont allow me access

[iMore Question]

If I go into music, (did the back up before the downgrade) and click on a song nothing works, it goes back to the homepage. How do I fix this I have synced, cancelled all music, did a reset, and still nothing works, please help as I really do need my music on my phone. I have tried everything. Everything else came across when I did the downgrade and restored my phone
