I'm now starting with manuals of Minim blog. At the very beginning of it, it is emphasized that 'before your program exits, it must close any audio I/O classes', and 'A good way to ensure this happens is to define a stop method in your sketch where you close all audio classes'. The below is a sample code to play back a file, in which I added a few print() commands to see the order of execution. The reason why I wanted to see the order is that in 'draw()' method, there is no line calling 'stop()' method. As I know, a method should be called in 'draw()' to be executed. What is I'm missing?

and also, I moved 'song.play()' inside 'draw()'..but the result is the same - just played once. Why isn't the file played over and over? It's different from when I draw something.

I'm afraid that I'm asking very dumb questions =(
