How can I get my albums to sort by track numbers in iTunes 11's expanded view? I've been trying to figure out why my track sort order is wrong in iTunes 11. I have track metadata, and sorting by Album in the songs view works fine, but in the expanded view my tracks appear in what seems to be totally random order.

How can I get this to sort by track number within the album?
I can make my iTunes show something similar, if I set some of the tracks in an album to a different Disk Number compared to the rest.



Try selecting one of the out-of-order tracks, then use File > Get Info to open the window I've shown here.  Is there anything different about the information for the out-of-order tracks?
