 Pretty simple: Convert any properly tagged flag file to an mp3 file, and
 see that the resulting mp3 file does not have its YEAR tag set properly.

 I tried:
 D:\temp\playlists>ffmpeg -i "04 - Punk Rock Song (German Language
 Version)).flac" -qscale:a 2 output\PunkRockSong.mp3

 As per the documentation, here is the result of the following command on
 my input file:
 D:\temp\playlists>ffmpeg -v 9 -loglevel 99 -i "04 - Punk Rock Song (German
 Language Version)).flac"
