They are simply tracked/edited music and I felt that their inclusion was unnecessary. but everyone wanted them so they are included in case you to. I do not place them in the set because, again, I don't feel they need to be there. You can frankly place them wherever you want. In chronological order or at the end as extra tracks.
The correct track listing is whats in the sets. I need to update a few of the files on the site... that txt file included... but the correct list is whats in the set.
