Hov got flow though he's no Big and Pac, but he's close
How I'm 'posed to win? They got me fighting ghosts

from Jay Z (Ft. Chris Martin) – Most Kingz Lyrics on Rap Genius

Meaning

Jay feels that the only rappers in his league are the deceased icons Pac and Biggie. How is he supposed to ever be considered the best when he’s competing against the dead?

Jay has controversially compared himself to Biggie before. On 2001’s “Hola Hovito”, he rapped, “If I ain’t better than Big, I’m the closest one”

Also Pac is a double entendre for 2pac and Pacman. Which is why he says hes fighting ghosts like pacman.

Jay Z in Decoded explains this line saying

This is no shot at Big or Pac. The truth is that you can’t compare us; Big only did two albums before he was killed, and Pac was still going through metamorphosis, who knows where he would’ve ended up. So when people make the comparison — as they always do — they’re comparing my work not just with the work of Big and Pac, but with what they could’ve been — should’ve been — and what their lives and deaths represented to the entire culture. Their shadows still loom over all of us who were their peers.
