How to add custom fields to product_details/flypage based on a query to a new

I would like to present on the detail description of the flypage a list of the songs titles present on several album CD which are declared as products in Virtuemart. The query shall be filtered with the function WHERE with a probable a JOIN function between Product_id of VM product table and the new created table jos_vm_mp3.album_id

I understand so far that this query can be added in shop_product_details.php with the tags at the end of the list .

In the fly page
Add the new created tags – {track} – {title}-{album} and a play link for each with Href function which enable each title to be played in a Mp3 player.

As I am not expert in Php I need some advise or help how I can create the query to the DB and added table jos_vm_mp3 and how to join with the jos_vm_product to get a filtering of the datas (title) for each album.
Thank you for your help.
