Album duration possible?

[entdgc]

@simbun just for completeness and for anyone else reading this thread a slight problem has come to light with the process you came up with earlier. Your process seems to identify and album simply by its title. So if there are several albums with the same name they get added together. So all the 'Greatest Hits' albums from several artists get combined and end up with an VERY long album duration. I have manually corrected these mistakes in my library but maybe there is a simple change you could make to the process for any future users? Maybe you can identify an album by a concatenation of Artist+Album?
