- From the Vorbis I spec:

A.1.2. MIME type

   The correct MIME type of any Ogg file is application/x-ogg. However, if a 
   file is a Vorbis I audio file (which implies a degenerate Ogg stream
   including only unmultiplexed Vorbis audio), the mime type audio/x-vorbis is
   also allowed.

And note there that's a slightly outdated version of the standard (I can't get 
to Xiph.org right now.) -- the correct mime-type is now application/ogg 
(which I thought it was David that went through and changed that).

Basically audio/x-vorbis is a correct mime-type for the overwhelming majority 
of the Ogg files that people come into contact with on a regular basis.
