I would like to play multiple strings in 1 string.  Is this possible?

What I need is a player that the visitor can click and it opens a new window that shows a list of songs/samples to play while the browse the site.

When I use the {mp3}12 Be Still And Know{/mp3} string:
1.  The padding throws off any text surrounding, making it unattractive to embed
2.  I can only call in 1 track

Anyone know of a good solution for Joomla! 1.5?
