If you use JEmplode to load iTunes encoded mp3 onto an empeg you have to convert the tag to v2.3 (or lower probably - I have checked all versions) ID3 tags. JEmplode doesn't seem to recognise the track number tags that iTunes creates. In iTunes 3.0 you select the tune(s) you want to convert the tags on and right click - the convert tags option appears in the context menu
