So, i have two ideas, and by using them you can use both of these functions for you app:
Add more songs to your app and add images and label, add btns of play and stop etc.
Now when any user clicks on play or stop btn, u can stop the music, for this you have to use
repeat while app variable playingblock
You can also use a count with function and tell user, how many songs they had listened till, for this, u have to first create an empty list variable and when user clicks on any music to play, you can add the music name to list, and on the screen, you can show user, how many songs they have listened, by
