Music! it soothes the savage beast, they say. Well.. sometimes. Trust me, I have children: It doesn't always work that way...
Click the 'Play' button to the left of each composition title to play that particular piece. Click the 'Stop' button to halt the music in mid-stream. If the song finishes and you want to restart it, click 'Stop', and then 'Play' again.
Yes, it's entirely possible to play more than one song at a time. Being the traditional non-conformist and all around chaotic guy that I am, I opted to leave it that way! But seriously: why would you want to?
