a plugin that lists all mp3 on my site?

Can anybody help me with a quick answer ?

I have been using a category plugin which pages up for me a neat list of all in each cat

<?php wp_cat_posts(8); ?>

I would love to have a list of all of the streaming mp3 ‘s that I have on my site. I post one for more or less every single article but a page that will list all of them would be great.

Is there any easy way of doing this ?

thanks
