Nah the history of dance vibes set was from the 12 pack as well. It's one of those willy wonker golden ticket moments were some 12 packs had the hardcore set and some 12 packs had the history of dance set, there is no oldskool pack and like I said I don't know which is the most rare of the two. I added the youtube link from my channel and added the tracklist in hoping it helps people out it's just missing three tracks. Cheers.
