I got bored with the barely audible paper-crinkling default sound in the
Recycle Bin. (Yes, it is late and I am tired.) I changed the default sound to that attached below. It's almost fun cleaning out my computer now. Maybe someone else will like it as well.
Just download the .wav somewhere easy to find, then go to Control Panel | Sounds and Audio Devices; under the Sounds tab, highlight Empty Recycle Bin and enter the file path or browse to it; click Apply and OK.
