Jesper is right
You require only your browser to make the change. Just open the page you created and click on View and on Source in IE.
IN the notepad type
Code:
<embed src="name.mp3">
and save the file. Embed src stands for embedded source.
Refresh IE and press Enter selecting address bar, you can hear the music or song.
The same code can be used to play movie files. only thing is that the name and the type of the file (mp3, mpeg, mpg) etc must be correctly given.
