abcde writes wrong play times to MP3 files

I don't know any solution to my problem. I don't even know the cause and have a hard time trying to find it. I am ripping my Audio CDs using abcde, which is, basically, working well. It is configured to create both FLAC and MP3 output files as I want to have a lossless archive of my CDs in case they get damaged or lost. The MP3 files are for daily use. Now to the problem: While the FLAC files get the correct play times written in their metadata, all of my MP3 files get wrong durations written in their tags. Here is an example exiftool reading (while it's basically for image files, it works with pretty much metadata formats, and yes, ID3 tag readers show the same results): $ exiftool -Duration * ======== 01 - Rock or Bust.flac Duration : 0:03:03 ======== 01 - Rock or Bust.mp3 Duration : 0:25:02 (approx) ======== 02 - Play Ball.flac Duration : 0:02:47 ======== 02 - Play Ball.mp3 Duration : 0:02:15 (approx) ======== 03 - Rock the Blues Away.flac Duration : 0:03:24 ======== 03 - Rock the Blues Away.mp3 Duration : 0:02:45 (approx) ======== 04 - Miss Adventure.flac Duration : 0:02:57 ======== 04 - Miss Adventure.mp3 Duration : 0:23:18 (approx) ======== 05 - Dogs of War.flac Duration : 0:03:35 ======== 05 - Dogs of War.mp3 Duration : 0:29:40 (approx) ======== 06 - Got Some Rock & Roll Thunder.flac Duration : 0:03:22 ======== 06 - Got Some Rock & Roll Thunder.mp3 Duration : 0:02:42 (approx) ======== 07 - Hard Times.flac Duration : 0:02:44 ======== 07 - Hard Times.mp3 Duration : 0:02:14 (approx) ======== 08 - Baptism by Fire.flac Duration : 0:03:30 ======== 08 - Baptism by Fire.mp3 Duration : 0:27:25 (approx) ======== 09 - Rock the House.flac Duration : 0:02:42 ======== 09 - Rock the House.mp3 Duration : 0:02:44 (approx) ======== 10 - Sweet Candy.flac Duration : 0:03:09 ======== 10 - Sweet Candy.mp3 Duration : 0:25:18 (approx) ======== 11 - Emission Control.flac Duration : 0:03:41 ======== 11 - Emission Control.mp3 Duration : 0:30:57 (approx) 22 image files read I just don't get the clue, why this is happening. Does anyone know a solution to this? **Solution** Thanks to Phreds hint on missing VBR headers, I discovered the reason for this to happen. As it turns out, lame's --nogap option was activated in .abcde.conf. It's mentioned neither in the lame manpage nor in the .abcde.conf comments (my version, at least), that enabling this option disables the Xing header. In the abcde manpage, however, this behaviour is mentioned regarding the -g flag. Corresponding variable in .abcde.conf is NOGAP
