2pac, Eminem, B.I.G, Rakim, Nas, Big L, Big Pun, Jay Z, Canibus, Bone Thugs, Busta Rhymes

But thats just me...

I think 50 can become one... but he has to have more under his belt. Only BIG can drop 1 album and be called the greatest. I still dont believe he was able to do that, then I play the tape (yes I'm old school) and I can see why.

My personal Fav is
MC Ricky D, The Grand Wizard, The Ruler - Slick Rick
Parts of 'La Di Da Di' have been heard in just about everyone I mentioned before...

Free Kobe!
