Since posting my question yesterday I've played a bit with my music files and find that the track number of an album is possibly one of the causes of the change in sequence of music files from MC to iPod when I synchronize. For example, when a single classical work is contained on multiple disks even though the playlist in my computer maintains the correct sequence of the music files, when synchcronized to the iPod, the result in the handheld is that all the track 1's are together then all the track 2's, then the 3's. etc.
I overcame this by changing the track numbers in MC. (i.e., if there are 12 tracks on each of 2 disks, I change the numbers of the tracks on disk 2 to 13 through 24.
However, when I create a playlist containing the works of one composer in sequence of when the work was written , this often requires the collection of multiple tracks from many albums. For example, Haydn composed 104 symphonies. these were ripped from as many as 25 disks, and the sequence of works on each disk does not conform to the number of the symphony. One disk may include his 90th, 46th and 104th symphonies. I have over 323 files in my Haydn symphony playlist. I maintain these in sequence on the MC by symphony number. To overcome my synchronizing problem I'll think I'll have to change the number of each music track on my computer from 1 to 323.
The simpler solution would appear to be a switch that would enable me to over-ride the the automatic track number by album synchronization to maintain the same sequence as exists in MC11.
Please let me know if my assumption regarding track numbers is correct and whether there is the possibility of providing the over-ride switch.
