Of course. But that's a different story. Indexing services of 
type 'metaExtract' do that.

That's also the case for mp3. Would you categorize it 'application' instead of 
audio?

For a mime type that's correct. For a system like DAM I would like to 
categorize all files that are 'text' to the user as such.
But this is open for discussion and as I wrote, it can be changed/customized 
easily in every installation. It might be possible to provide two base 
configurations: "official mime type" "modified media types"

From my point of view media types is not the same as mime types and may 
differ.

Yes.
BTW: the official mime type list is missing file types, too.

The mime type list is used by different applications like the webserver 
(apache) for example. Often there's a shared mime type list, but not always. 
So mime_content_type() is not reliable. That's why I use my own list.

I'm happy to add missing types when you send me

extension, mime/type, media type
example:
mp3, audio/x-mpeg, audio

If one want to review the full list, I'm happy too
