Comment (by dslkjlskdjfllk):
Ok, let's try this again. It happens 100% of the time, with any file. I
take a flac file and convert it to a mp3 file and, magically, the "year"
tag disappear in the resulting mp3 file.
Here it is:

I see here that the date tag is set to 2010.. as the original file. But
when I play that file in winamp, the "Year" tag is empty in the mp3 but
filed in the FLAC. When I inspect both files in mp3tag, I get the same
result: The year field is set for the flac, but empty for the mp3. Is it
the case that the id tag is not properly built?
Thanks
