The custom sort title replaces the title for the purposes of the library screen.  This is to ensure the item is placed where you want it to be in the list. I thought it made more sense to display the song based upon the sorted title versus displaying the normal title but placing the song in the location where the sort title would put it, as it might otherwise be a little confusing (and the logic would get even messier than it already is for processing the sorting/alphabet list).  The normal title is still used for the overlay and setlist window. If this is not intuitive to people, or people think it would be better to not display the custom sort title (but still use it for sorting purposes), I'm amenable to that.

Wouldn't adding an title format field %SORTTITLE% solve this?
