I already did the BBS post about it, but why not bringing even more attention to it.
NG Megamix Collab is meant to be a tribute to some absolute classics on the portal, ones that became iconic and, in some way, synonymous with Newgrounds. The idea is to create songs using samples from legendary NG tracks in order to make your own.
Why?
It might sound wrong to some people, but I believe using somebody's work in order to make your own original work (e.g. through sampling and crediting/mentioning it in a positive way) is the highest form of honor. I've been on Newgrounds for almost 3 years at this point, and I wanna pay homage to people that made NG's legacy through Audio Portal.
