// flash MP3 player actionscrip.  works with an xml playlist and a  flash movie containing 
// 4 labeled buttons:
// play_btn_1
// pause_btn_1
// stop_btn_1
// next_btn_1

// now some fun slider stuff


// a text field is generated to display the Song title from the ID3 tag.  if the ID3 tag is 
// not avalable the file path/name are displayed instead.  i dont know about itunes and ID3 tags...
// 

// please note this is all action script 2.0
