Eminem is a diehard lyricist and worships lyricism so much that he calls himself a "rap god". I'm that song he lists his favorites at that time not of all time. Jay-Z respecting Andre 3K's lyricism is dope but if you ask him for his top 5 he picks Big, Pac, G rap, Marshall Mathers and KRS.

If you ask Eminem for his top 5 he goes completely old school:
"LL, Run DMC, Beastie Boys, Kool G Rap, Big Daddy Kane, Treach"

But no Andre 3000. I'm not saying the man ain't talented but he's not top 5 of all time.
