This Blue-Head makes a good point!
the amount of time it would take strange to box up every strange release into a single package would cost a lot. and then they would have to sell it for like 200$...
i think far less people would be interested in buying this than you think. i know i wouldnt buy it, why spend a large amount of money just to get duplicates of 90% of the packages contents.
It would make more sense to make a box set once he's done making music so EVERYTHING he puts out is included
