// OK to use if this notice is included
// This function reads an MP3 URL and title from the referring page and generates embedding code to play back the audio file.
// Windows browsers (except for Internet Explorer) will play back the file with the Windows Media Player *plugin.* Internet Explorer will use Windows Media Player.
// Non-Windows browsers will play back the file with their standard audio handler for the MIME type audio/mpeg. On Macs, that handler will usually be QuickTime.
