HA!... i solved my own problem. I found I could accomplish the same thing, by making each song link to a non-visible frame, that would load up a page, with the embeded Media player, that would autostart the file, and then made a link, to act as the stop button, that would just load a blank page, on the same invisible frame, therefore cancelling the song.
all that javascript hooo haaa, was not needed.
