Yes, the collection is a luxury item. Just because you are buying a luxury item does not give the producers the right to misrepresent the product. If you buy a Stradivarius violin, it should be a real one and not a replica - especially if you are led to believe it is in fact, a real Stadivarius.
Any expectations about this collection were set by the producers comments. Clearly one of them or more of them said "We're not modifying anything, we're preserving things" -- So that begs to ask
why say that if you are planning to take editorial liberties with the set? The original soundtrack and "selections from" the original soundtrack are different products.
