Ok I've looked around as much as I can for this but to no avail.

I'm trying to figure out how, or if it's even possible to, randomize the sounds in the UISound folder, i.e. have the theme play a different sound each time I lock, unlock, etc. it. I know how to get the wallpaper to randomize and was thinking if I could apply the same properties the the effects in UISound, but have been fumbling around with it for a bit to no avail.

Has anyone ever done this before? Any information would be very helpful...

As a side not, not looking for an app or addon that will do this, I'm trying to get it so I can put it into the folder for my theme so that no matter who installs it, it will work. I don't much like having to hit all those switches to complete a theme.
