Hello, I have two problems: One, i downloaded some mp3 music files to my phone and saved them in the music folder. However, they do not appear in the music app. How can i remedy this? Two, i purchased music through the play market, but i do not want to use the 'play music' app. I want to use the 'music player' app as it its easier to use. How can i remedy this? Thanks for your answers!
