Free MP3 Download Store w/ WordPress

What I want to do is have a portion of my store where users will be able to download mp3’s freely (without having to go through paypal or checkout process). Seems that there are no plugins for wordpress that can do this without modifications. I want to achieve this with WP-Ecommerce. I’ve searched the forums, but none of solutions that users have came up with actually seem to work.

If anybody is knowledgeable with this plug-in can you please help me with this. OR if there are plug-ins that I’m not aware of that can achieve this pleae let me know.
