Oops, I wrote a response to Jorn's email earlier, but I accidentally
replied off-list.  Yes, MusicBrainz has TRMs which are signatures
calculated based on the audio content, as well as unique IDs for each
artist/album/track in their database.  

The storage of these values in metadata isn't a standard in the sense
that ID3 itself is, but since ID3v2, Ogg, and FLAC all allow for custom
comments frames MusicBrainz came up with their own specification for how
they store their data in these fields:
http://www.musicbrainz.org/docs/specs/metadata_tags.html

So, if you want to store/read MusicBrainz tags you should follow their
guidelines.
