If there was a previous discussion about this, could someone point to it in the archives?I tried to find the discussion but I was not able to find it. Maybe there has neven been such a discussion on the internet. As I already said: IIRC ;-)
I have filed this as a bug: https://bugzilla.gnome.org/show_bug.cgi?id=690297
>But the field "Orig. Artist" fills "PERFORMER": >PERFORMER=222222 I suppose that this comes from a misunderstanding of the PERFORMER field: http://www.xiph.org/vorbis/doc/v-comment.html “The artist(s) who performed the work. In classical music this would be the conductor, orchestra, soloists.In classical music that's the artist ;-)
Not according to the Vorbis comment section linked to above, which describes the ARTIST field as:
“The artist generally considered responsible for the work. In popular music this is usually the performing band or singer. For classical music it would be the composer. For an audio book it would be the author of the original text.”
I filed a bug about improving the handling of ARTIST and PERFORMER fields:

>And the field "URL" fills "LICENSE" >LICENSE=444444 This seems wrong, unless the URL specifies the license that the work is under. There does not seem to be a good URL-like field name in the Vorbis specification, so I suggest that the URL field in EasyTAG saves to a "URL" field in the Vorbis comment. If you agree, I can file a bug about this too.
For Vorbis tags, I think that the URL field should probably map to the "CONTACT" comment field. I filed a bug:
https://bugzilla.gnome.org/show_bug.cgi?id=690301
Thanks for bringing these oddities up. I suppose that much of the problem may be in what players and metadata viewers map the field names to in a UI, so any information on what those classes of software (or specific applications) expect would be useful.IMHO we need an RFC for tagging.
I think that the Vorbis specification for comment fields fits with my position on this topic:
“It is meant for short, text comments, not arbitrary metadata; arbitrary metadata belongs in a separate logical bitstream (usually an XML stream type) that provides greater structure and machine parseability.”
However, I think that EasyTAG should be flexible enough to support custom tags, and there is an open bug about that:
