If I delete the app, would my music be deleted? Basic info: my phone is Alcatel One Touch Fierce 2, and the music goes from the app to my actual music app on my phone (playlist) so and so.
Yes, you can delete the application, because the music files are stored on your phone. You can actually install a new application that plays music to load all your files. Access Google Play Store to install other applications that can play music files.
