This looks like a misdetection instead of a query problem. The simplest 
solution I see here is to attach more than one MIME type to each file. 
For instance, an Ogg Vorbis file could be application/ogg and also 
audio/vorbis.

Or, if you'd rather, you can have compositions like:
Content-Type: audio/vorbis; container=application/ogg

Content-Type: text/plain; charset=utf-8
Content-Encoding: zip

The detection of M4A files as video/* is just plain wrong, OTOH. If it 
doesn't contain a video stream, it mustn't be in video/*.

Now you'll ask me: what about a (for example) AVI container with Theora 
video and MP3 sound? Should it be application/x-avi (or 
application/x-mplayer2), audio/x-mp3 and video/x-theora? Well, I don't 
know. I guess it really depends on the use-case and what you need this 
data for.
