Hello,
For multiple MP3 files in a folder, how to define the Title tag field with: "filename duration in sec" ?
EXAMPLE: song.mp3, duration 3min 10sec -> Set title: "song 190"

If MP3TAG cannot do this, what MP3 tag editor can do it?

Thanks and regards.

CONFIG: MS Windows 7 SP1. MP3TAG 2.49b

Action: Format Value
Field: TITLE
Formatstring: %_filename% %_length_seconds%
