When I recently switched to mac and iTunes, I unchecked the boxes in the iTunes preferences that would allow iTunes to manage folders and add files into the iTunes folder, because I wanted to keep my files and folders organized as I have long had them. Then I added all my folders to the iTunes library. So far so good. The problem: Much of this music is classical, where it is vital that it be played in a certain order. (Movements of a symphony or choral works, for example) To preserve that order, all my individual mp3 files are numbered: 01...02...03 etc. Despite this, iTunes lists files in a seemingly random order, and no matter whether I click on the title, or album or artist column, I can't get iTunes to list files in the order in which they are numbered in their file names. What to do? How to get iTunes to respect the numbering of my files?
