id3v2.3 multiple genres?

[CyberWilhelm]

Hey guys, another quick question for the group. What is the preferred method for separating out multiple genres in ID3v2.3 headers?* I haven't been able to get minimserver to recognize them.

Browsing the archives, I found references to the fact that MP3Tag and most other programs seem to write the TCON frame incorrectly, but I haven't been able to figure out what "correctly" means in this case. id3.org gives guidance for referencing multiple id3v1 genres, but stops short of saying how to do multiple free-text genres. Aside from not separating them with null values, and not defining multiple TCON frames, anyway.

I've been using writeAllTags to help debug this, just to factor out potential control point problems and make sure that the tags are/aren't getting recognized by minimserver how I want.

Thanks for any help!

*I'm guessing the actual preferred method would be to use ID3v2.4, but I need my to use ID3v2.3 for other compatibility reasons.
