XSPF music player not working on website

[jczebra]

I attemped to use an xspf music player from http://musicplayer.sourceforge.net/ on my website at zebrathieves.com. It opens in a new window from the "listen" link in the navbar. The problem seems to be that it won't load the playlist.xspf file, though I'm not sure this is the issue. Would a glance at my source code indicate any obvious problems?
