Depending on the other music app you are using (other than the Music Player), the (play/pause) button on the unit may correspond for both options.
That means that music may overlap, since the Music Player and the other app may both start when pressing the (play/pause) button.
To play music on a different app than the Music player:
- Press the (play/pause) button on the Walkman, then pause the music that has been overlapping.
- Play or pause the running player app by operating on the app screen.
