Hi,
I have a huge collection of .aif/.aiff files with music bought from places like Junodownload and Beatport, and they're all ID3-tagged using MP3Tag. I noticed, when making playlists in VLC, that for most files, the "Genre" information is missing.
According to MP3tag, the files utilize the ID3v3.2 container, and genre information is stored with value = $meta_sep(genre,\\) and field %genre%.
Cheers,
Tord
