Lol that's like saying if i paid for an mp3 and so did you we can swap, don't think it works like that "not that I give a fuck" sample packs are sample packs, samples originally stolen in the first place lol........just look at that amen break sample and how many jungle producers even own a real drumkit?
theres a lot of big accusations going around here, saying sample packs are all just stolen sounds is a bit far fetched. bass loops/ one shots, atmos etc are all created by the producer that made the pack.
as for swapping, it is legally and morally wrong. if you think its worth having, buy it. otherwise only 1 copy of each would sell, and everyone would swap
