[sciurius]

I've received a number of requests for displaying the combined duration of songs in a setlist (along with dividers that can be used to show duration up to a certain point in the setlist), so it seems to be something that a lot people would benefit from.  I'm going to try to make time for features like this soon.

Thank you!

As for automatically populating duration, I actually already support this.  You just have to enable the option to populate metadata when importing audio files.

This I usually avoid since I do not want the song fields to be overwritten by bogus song metadata. Most of my song audio files are home-made recordings and do not have sensible metadata.
Song duration OTOH is not metadata from MP3 tags, it is calculated.
