I've spent a few hours searching here and other forums but I can't seem to find anything on this, which means someone will probably respond pretty quickly with a link to exactly what I was looking for.
I'm in the process of cleaning up my mp3 collection using MusicBrainz Picard as the first step. I have both Picard and Mp3tag set to use ID3v2.3 (in addition to v1). Picard seems to have an "Artists" tag where it stores multiple artists for a track, using either the ; or / separators.
I've tried adding the "Artists" field to Mp3tag, after opening some tracks tagged by Picard, but Mp3tag doesn't list the "Artists" field anywhere so I can't add it. I'm probably missing something pretty simple here but I'm stuck and would appreciate any help offered.
