When you start playing a song, you can't exit.

Exactly, this is due to the logic of how the beeps are executed, I initially tried a way to check if a key was pressed and if true, exit the music, but I was unsuccessful. So the only way to exit the music so far is by restarting the Cardputer, but this is not a convenient way. A solution needs to be found for this.
