use JW Media Player in articles

[mumpsimus]

Hi there,
I'm new to joomla and there may be an obvious answer to this question
so I apologize in advance.
I would like to use this player in multiple articles where a single
mp3 will play. Each article will link to a different mp3 - it's for a
radio show website. I am using {loadposition} to get the player to
show up in the article but I'm stuck as to how to point to the right
mp3 for the article. I see in the module parameters you can point to a
file but I need to point to a different file for every instance of the
player.
Hopefully this is possible.
Any help would be greatly appreciated!
Cheers,
Nancy
