It occurs to me that you might want to provide your web page users with a mp3 
audio player, which is NOT part of the Display Utility above.  An example of this 
can be seen by clicking THIS LINK.  To hear it play an mp3, type in "whatever.mp3"
(without the quotes) - that is one available on my site (in the same folder as the player). 
Here is a link to a zip file that gets you the web page and the 
             Flash movie that is the mp3 player

(Following the directions AT THE END OF THE SECTION ABOVE tells you 
how you can embed this mp3 player within an area on one of your own web pages.)
