CD track lengths

I’m trying to get the CD track times/lengths for the CD artwork - so I should be looking at the “total” line
from the CD montage report, right?

Yes, though this might include pauses.

What exactly is the pause? The time between the end marker of one song and the beginning marker of the next?

Also, once a CD is pressed, the underlying clip is irrelevant and the “new” files are essentially where you put the markers in your montage?
