Why can't I listen to my music on my Iphone 5?

Whenever I open my music app, it will sit at the main page, and when I touch a song to play it (whether on the all songs list, or in a playlist), it doesn't play the song, and the app freezes. When I plug it in to my computer to try to reset my iphone, and I click on the iphone icon, my itunes freezes. When I go into my iphone settings, and touch the music settings, my settings app freezes.

Reboot your phone?

It sound that the music app has some problem that caused the problem. Try uninstall and reinstall the app.
