The music app is not closed.

Extended information:

Solution to the problem that music cannot be opened:

1. First try to open it again. If it cannot be opened, check the network. If there is no network, reconnect. Open.

2. When you can’t open the unwanted music even though you have the Internet, friends need to check if there are too many software running on the phone, clean up the junk on the phone quickly, and then open the unwanted music.

3. If you still can't open it, you need to wait for more than ten minutes (the music may be being upgraded if you don't want it). If you can't open it after waiting, you need to change your phone (cross it out) and change it to suit your friends. No music version required for mobile phones!
