Music Preview on Product Listing Page

[Natedogg]

I would like to have a music preview on the product listing page similar to these sites:
Modern Beats
or
Mouzika

Any help pointing me in the right direction would be helpful!
What files am I going to need to modify? I know a little PHP so I can make some edits but, I am not even sure where to start.

I need the same info. I craft and sell "tuned" wind chimes so it's important for the customer to hear the chimes before purchasing. Thanks in advance!!
