On "Ether"—one of the most vicious diss songs of all time—Nas took plenty shots at Jay-Z's sexuality and street credibility, but the line that burned extra slow was, "Eminem murdered you on your own shit." So props to Nas for coining the term that inspired this list. And by the way, there's no denying that Nas was right.

Most of Jay-Z's album The Blueprint was built on soul but for some reason he opted to rhyme over one of Eminem's trademark haunted house tracks alongside Marshall himself. Maybe Jigga wanted to prove that he was the Best Rapper Alive by rocking with The Next Best Rapper In Line? Either way, Jay held his own but Marshall spazzed, spitting one of the best verses of his career and owned Hov on Hov's best album.
