Thank you DFELD2005 !!
That seems to make a very large difference. I do the same thing by getting a audiobook from the library, and some are very large, so there are a lot of files. I have all of the files sequentially numbered with the title, filename, and track going in order, usually starting at 1000 to avoid the leading zeros and to accomodate all of the tracks. Like I said, this has worked perfectly before, but not with the Sport. I updated the files to go by Album (I only had one album before), and changed the titles to “Chapt 01”, etc. with the track getting the cooresponding number. This actually worked! This is the first time I have had the tracks play in order on the Sport. I am wondering with the track numbers being so high and so many under the same album if it just couldn’t process that properly… I guess I will be breaking them up by album in the future. Thank you so much for the help!! You have figured out the trick
