Safari Errors and my MP3 Player

Hello. I created an XML powered MP3 player that seems to run flawlessly on all browsers except Safari. I mean, it still works like it should - but then I get those pesky little error messages in the bottom left corner of the browser.

The Safari error messages only occur when I click the next button before the current song has completed loading (the songs stream). And the error message says, “Operation could not be completed,” then it references the URL to the song I just skipped.

I’ve tried adding a few lines of code to communicate to the browser that it’s okay to stop loading that song if the user selects the next one:

for example, I’ve tried:

my_sound.stop();

and I’ve also tried:

unload(my_sound);

I don’t even know if that last one is correct - but either way, these did not work… Any ideas??
