Display sample download file in category view

I have a magento storefront that has just downloadable products. In my design, all products are displayed in list view. On that list view i need to have a button to play the sample audio file from the downloads. I've been unable to get the sample track to display in the category view. So im looking for an experienced Magento developer to help set that up. I would like to use the Wimpy audio player to be able to play and stop the audio file in the list view.
