Hang on. When you rip an album on the Central, it doesn't make a playlist. Playlists are something you have to create yourself. "Position" has no meaning in a soup entry on the central itself, it only has meaning for playlists. How did you create the playlist?

Maybe it's should be a feature request where jemplode should use the track number as the basis for the postition when displaying stuff like albums and artists. Dunno how it handles that.
