If you use the time format, you can simply sum these, just make sure you
format the result as [h]:mm:ss to allow for more than 24 hours.

I am trying to set up a worksheet with all of the music stored on my
computer, with the total duration listed. Is there any way to set up the
SUM() function so that it returns this value, or do I need to use a
different
function?
