I'm having issues with the music app in iOS7, basically the app won't open. I have a 4S 16gb, when I go to open the music app it opens a blank white window which stays open for a good 20 sec without doing anything, and then it just goes back to the home screen. I've tried rebooting the phone, playing around with the settings in the app, etc but no luck. I do have iTunes Match. It also works fine on my iPad 2. Any ideas? Anyone else having the same issue?
