You're probably just thinking too complicated. From SimpleHTTPServer:

     def do_GET(self):
         """Serve a GET request."""
         f = self.send_head()
         if f:
             self.copyfile(f, self.wfile)
             f.close()

Let's adapt this slightly (untested):

     def do_GET(self):
         """Serve a GET request."""
         self.send_header("Content-Type", "audio/mp3")
         self.end_headers()

         my_mp3_file = open("Metallica - Nothing Else Matters.mp3", "rb")

         # Reading the entire file at once is probably not that great a
         # strategy.
         self.wfile.write(my_mp3_file.read())

         my_mp3_file.close()

This would probably quite a boring MP3 server, always serving the same 
file ;-)
