When KRS already made an album called Blueprint
This refers to Boogie Down Productions' album Ghetto Music: The Blueprint of Hip Hop, which primarily featured KRS-One.
“Takeover” was featured on Jay’s album The Blueprint, so Nas is accusing Jay-Z of being a copycat.
In addition to taking the name of the album, Jay-Z samples KRS-One’s “we run New York” from Sound of da Police on the Takeover.
