Irv Gotti 'questions Eminem's rap legacy'

Inc. Records head Irv Gotti has insisted Eminem's longevity is questionable, reports say.

The label executive addressed his disappointment with Vibe magazine naming Slim Shady the "best rapper alive".

He told MTV: "S**t like that kinda pisses me off. You know why? Because let's take Eminem's records. Watch my analogy. Eminem is a great artist, no doubt. He puts words together, he's witty, a smart lyricist, a great lyricist. But how can we say the guy is the best rapper alive?

Gotti also remarked that Eminem's albums are no comparison to previous efforts by rappers Jay-Z and DMX.

"Look at Hov [Jay-Z]. I've been to battles with DMX, Jay-Z and Ja Rule, that was some real s**t. Homie, you wouldn't been able to survive. I say take Eminem, and let him say 'Hard Knock Life'. Still hot. Now, let's have Jay-Z say the 'We Made You' song. They would laugh him out the f**king building. It would be over."
