[Longtime Collector]

I knew all my mp3's were tagged with genre, yet Kodi was not picking them up. I found Kodi skips genres for any mp3 having duplicate genres (e.g., Pop|Ballad|Pop). If you use Florian's Mp3Tag to fix your mp3 tags, here's the Export Configuration to count genre-filename, looking for duplicates. It creates a batch file Tagcount.bat, which you run (by answering Yes at the prompt) to get your taglisting.txt file with the counts.

DupSongGenres.mte

Code:

$filename($getEnv('USERPROFILE')'\desktop\TagCount.bat',ANSI)
@echo Off
chcp 1254
if exist "%%USERPROFILE%%\Desktop\taglisting.txt" del "%%USERPROFILE%%\Desktop\taglisting.txt" /q
REM Create a Newline variable (the two blank lines below are required!)
set LF=^

$loop(%_filename%)
set "string3=%_folderpath%%_filename_ext%
$if(%Genre%,set "string=$replace($meta_sep(Genre,|),'%','%%')|%string2%"
    setlocal enableDelayedExpansion
    SET string2=!string3:^&='^^^&'!
    SET string=!string:^|=%%string2%%%%NL%%!
    echo !string!>>"%%USERPROFILE%%\Desktop\taglisting.txt"
