This is a never ending debate which, I can never decide on there are so many MC's that could be in that top 5 and still to this day I can't decide on who should be in it. I guess for me there would be 2 lists on for Mc's from the golden era then one for the current heavyweights. Anyway in no particular order

1. Biggie - the king of BK
2. Kool G Rap - Ill street blues need I say more
3. Big Daddy Kane - This guy was the shit back in the day
4. Lord Finesse - After I heard him murder Percee P on the freestyle tape from 89 / Rakim - too hard to pick between the two for me
5. Nas - ever since nasty nas

Honourable mentions: Elzhi, J-Live, Talib, Mos Def, Black Thought, Common, Phife Dawg, Big Pun, Erick Sermon, Pharoahe and large professor
