Hi,
The best way to do this would be to upload a copy of the mp3 to your server and play the sound locally. If you don't have permission to use this, then I would stay clear personally.
The best method for doing this would be to have the tracked called remotely, iFrames could be used, but you'd be better off having the player files hosted locally.
Have you got a link to the track and will it be subject to change?
Michael.
