Is there any discussion of the total set of ID3 tags/fields and
possible/desirable intergration?
The reality is that MP3 files are very popular and most are ripped (legally
or not) from commercial audio CDs. Allowing this index to closely mirror
the ID3 fields and tags seems like a good idea. Granted, the ID3 genre
field is a mess but a limited one. The others, year, publisher, copyright,
media and more are worth a look.
