I have messed with this thing for hours and cannot figure it out. I synced 612 language learning mp3s, divided into 55 separate Units. Each Unit is meticulously tagged such that it goes in order from Unit 1 to Unit 55. However, no matter what I do, this stupid thing refuses to display them in order. Itunes has no problem displaying them starting with 1 and going to 55, but the iPad always swaps the 55th unit and the 1st unit. Maybe this is a little OCD, but I just can't fathom what would be causing this. I mass tagged all 55 units with the same genre, year, and artist. The only other information in the tag is the name of the album, which are all Unit 1, Unit 2, etc. and the track numbers (each Unit starts at Track 1 and goes to whatever). Any ideas? The only thing I did find to "fix" the problem was to set Unit 1 to year 2004, Units 2-54 to year 2005, and Unit 55 to year 2006. This looked good, except then it took some random unit like 44 and moved it out of place. Thanks!
