There was a long remix type song I used to love 5+ years ago, found it randomly while using limewire, can't remember anything about it, maybe Papoose was in it. Anyway I'm hoping someone happens to post the song I'm trying to remember

I can't remember the name of it but Eminem remixed a Biggie/Pac song I think. Heard it a couple times was one of the sickest ones I ever heard. Or this one https://www.youtube.com/watch?v=212f5Vz5BBs.
