As far as I know the Genre is internally encode as a simple number in a MP3 header.
MP3tag shows in the column "Genre" the corresponding Genre as full label text.
It works in Mp3tag. However in (other) audio players (on Android) I got some strange values as Genre. So would like to peek directly into header to get the real internal Genre value for further investigations.
How can I tell Mp3tag to show me this number (and not the interpretation)?
Are there differences between ID3v2.3 and ID3v1 Genre encodings?
