Whoever said, "Just cause you started listening to rap 3 years ago doesn't mean NaS isn't mainstream". Is right, I will dap you when I find the post. The issues is NaS in the last 10 years hasn't been really mainstream, he's completely ran away from it. Sure on his album he will have a mainstream track or two, "Make the world Go Round", "Summer on Smash" these are Nas's attempts at the mainstream. But him as an artist has moved further and further away from the mainstream. He even said on "Testify":
"F*ck ya'll little hoe b!tches, I don't need y'all I'll go Gold wit it"
But as I said, NaS from about 95-2002 God's Son era was pretty Mainstream, meaning he was known in the public and getting radio spins. I mean by "NaStradamus" even Diehard NaS fans were feeling he was long gone from the streets. NaS made a calculated decision after "ILLmatic" and Steve Stoute helped him get to that decision. Was he going to be a Street/Underground rapper or could he think Bigger and go beyond. NaS even said this when discussing "Ready To Die" and how it blew and changed his state of mind:
