Hello,
I recently noticed in MP3Tag that the ‘LENGTH’ field is no longer available in the Extended Editor. I have to add this field manually.
Is the LENGTH field no longer supported in MP3s?

The MP3tag variable to address the length as it is written by the ripper is %\_length%.
For me it is inexplicable, why the mp3 standard has a freely editable field called LENGTH which only by chance shows the correct length and if the converter cared to write it.
So, if you want to see the real length of a track, use %\_length% and not %length%
