Try adding mp3 content type header: 
Content-type: audio/mp3
It is likely that some of your users' IE browser would default to a document type unless one is explicitly specified. 
Update: didn't realize you half answered your own question there, heh!

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
