XSPF Player works in FF not IE?

i embedded the XSPF player on my webpage but it only plays in firefox, wont do so in internet explorer.

The player is embedded in an iframe on my main page. the main page is http://www.reefscavengers.com and the iframe loads http://www.reefscavengers.com/test.html which is where the player is embedded.

any help is appreciated!
