Changing playlist on mp3 player

1

This is just a quick question.

I made an mp3 player for my bands site. We’re coming out with a new album, and i was wondering if theres a way to change the XML file thats pulled up when a button is pushed. this is the code i have so far.

  playlist = "playlist.xml";
// playlist loading
data_xml = new XML();
data_xml.ignoreWhite = true;
data_xml.onLoad = loadData;
data_xml.load(playlist);

Theres one snag though. I load the player.swf as an external swf from the main.swf file. Is there any I can send the command from the button clicked to the player.swf?

thanks for any help
