Not a problem, the vorbis comment header is completely extensible. 'ISRC'
sounds like a good tag name to me. I wouldn't suggest we canonize it yet,
but you should definitely go ahead and use it in your ogg files. (Like
CDDBID) it sounds like a great way to identify source material.

Players may or may not do anything useful with it, but none should have
any problem with it.

Is the ISRC meant to label recordings, or just particular publications of
them (like the UPC codes)?

FWIW,

Only 46655 labels per country? Someone wasn't thinking ahead. The
two-digit year will be a scalability problem as well. Too bad. :-/
