[FFmpeg-user] How do you use Ffmpeg to give unique title/track names (%02d) using -metadata to a split .mp3 file?

[Dave F]

I'll take a look at your suggestions, thanks.
However I disagree that ffmpeg isn't the correct tool. It allows 
read/write access to the metadata. I can add track titles to the files, 
just not unique ones, automatically.

Something seems amiss.
