Rap God - Eminem is a rap god.

I can second this mate - The way I see it, is that anyone can rap at a fast speed but it doesn't make them a "rap god".
For example:

This came out in 2011, and just listen from the time 2 minutes 10 seconds.

Well my opinion that Eminem is a great rapper, though that video is good aswell.

Of course mate! We all have our opinions, I guess, well who I see as a "Rap God" is Tupac Shakur but not for the speed of the rap but for what he to say.
