Good but... – Music Factory - Review

The app used to work fine, no crashes but now I have to close the app, restart the app and choose another song instead of just hitting choose another song. Keeps a little annoying and frustrating. Would give it a better review if I didn't have to do that all the time. Is a good app to practice songs with though.
