Multiple genre-tag / ID3-Version

[Lakorus]

Okay, I found that MusicBrainz Picard is setting the ID3V2.3 tag properly, so that MinimServer shows the multiple genres and my project can continue. As a preset, Picard only has "genre" and I had to manually add tags with slight variations ("Genre", "GENRE") in order to make it work. Those tags are recognised as multiple tags by MP3tag.

My next problem is that I haven't found an easy way to retag the files by batch yet - the scripting tool is beyond my comprehension at the moment. Ah well, step by step...

Thanks again.
