It’s debatable if it’s a low-key diss, only Nas knows. He said they’re the smartest not the loudest. Everyone and their grandmama knows Deathrow was talking shyt about EVERYBODY.
The line can be taken for what it is, Nas ain’t ever been shy of a subliminal, even if he treats Pac as one of his goats
I think it was a pushback to one of Snoops many versions of the story. Snoop was sayin that Pac was screaming on Nas.
