Debian unstable does this:

$ file Tori\ Amos\ -\ Sister\ Janet.ogg 
Tori Amos - Sister Janet.ogg: Ogg bitstream data (maybe Ogg Vorbis compressed au

(Yes, it actually truncates at 80 columns, even if I manually set COLUMNS
higher than that.)  Here's the entry from /usr/share/misc/magic:

# From Felix von Leitner <leitner at fefe.de>
0	string		OggS	Ogg bitstream data (maybe Ogg Vorbis compressed audio)

Apparently, getting any information about the Vorbis stream requires some
non-trivial operations that aren't suitable (perhaps not even possible)
for the magic(5) format.  But I'd be delighted to be proved wrong.
