// This is a rewrite to attempt perfect code for the HoG radio.

// 1/31/2006 my 2 day of actionscripting
// The logic is quite simple after writing it down.
// This movie clip is the controller of everything else.


/* This is basically the logic i have come up with
Start
Switch vars loaded?
	no
		Switch am i already loading?
			no
				load vars
				set loading flag
	yes
		print song info
		calculate timer
		switch time = 0?
			yes
				set loaded vars to false
				set loading flag to false

/* I leave this version by noting the following hopefull updates.
The display information needs to change as it is being updated.
It should count down from 15 and display the info in the screen.
Even more possible a status bar displaying the data.
