At the top we have 7 buttons, with targeted links.
Functions:
The single screen app has 3 main buttons, tap, pause and exit.
Play button: Plays the music.
Pause button: Stops music.
Exit button: Completely exits the application.
Note: The back button on your Smartphone after clicking the app goes into the background freeing your screen for other uses without disconnecting from the radio, so you can see other things while listening to the music.
