why are my tracks out of order ?

Many of my tracks are out of order, I can't figure out why. For example here are my Steely Dan tracks, as shown by either an album or artist sort.

Image shows not much. Make sure the Album Artist for all tracks on an Album is the same. Also make sure you don't have incorrect values in the Disc# field.

hey thanks ! somehow the Disc# field got filled in on the last tracks. Problem solved !
