The music collection is perfect

The music collection is perfect
I have tried so many relaxation music collection and Finally I found this app.
in this app , we can setup time to music to stop after time , but there is only problem in music time setup, each time we should change it , I mean It doesnt save the settings to use in the other musics,
Thank you for nice app.
