Podcast and Audiobook files not in order on Jam

Thanks for your response.

I think I’ve tried that, with no luck. What I did:

I have Vista, and no tag software. I right clicked on the mp3 file and selected ‘properties’. I then clicked on details, and in the track number field - represented by ‘#’ - I deleted the number and left it blank. I tried this on six files, which were episodes 7-12 in a lecture series. Each file’s name begins with ‘Lect’ and then the lecture number. So, ‘Lect 07: Socrates on the Examined Life’, ‘Lect 8: Can Virtue Be Taught?’ and so on.

I dragged these files, none of which now showed a track number, to the Podcast folder. When I navigated to them on the Jam, they appeared in the order 7, 9, 11, 12, 10, 8.

Is what I did at all related to the ID3 tag?
