Mp3 Player filter to load files

[CarnagePHP]

Hi im new at php and i uploaded to my server a flash mp3 player with a php freeware (http://www.realitysoftware.ca/portfolio/websites/flashmp3player/)

and it works fine, but besides my mp3 files it loads another files, does anyone know how to filter this files to be loaded and only leave the mp3 files?

the php file gives me the option to include an array of excluded extensions, something like this:

<?php

 

//player will not scan this folders

$exclude_files =  array(

"_derived",

"_private",

"_vti_cnf",

"_vti_pvt",

"vti_script",

"_vti_txt"

);

 

 

this link shows an example
