Rap God - Eminem is a rap god.

I don't know aboput a rap god, there are many before him that blow him out of the water. I am not saying he isn't good by any means but by no means 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.
