Is it possible to add music when a viewer decides to view the images in a slideshow mode?

There is a mod named "Music for your site (http://forum.coppermine-gallery.net/index.php/topic,11106.0.html)" that will allow you to add music to your gallery, but if you want to hear my opinion: music sucks on web pages - I prefer to listen to my own music when surfing.
It should be pretty easy to come up with some music while the slideshow plays - just modify the corresponding code in include/slideshow.inc.php as you see fit.
