I can not play music in Apple Music

I don’t know why I can not play the music in Apple Music. Frist because it is my first time to using Apple Music so the Apple Music is free me to use it 3 months. After I singed my Apple ID and I can not play any songs even though I have already download it. So I think It May be because it is free that’s why I can not using it. So after that I going to iTunes and App Store to unsubscribe Apple Music for free 3 months. And I have to perches in 1 month by using my VISA card and it still can not listen the same.
