Before you get all your panties in a bunch this is not my list. This list was composed by Kool Mo Dee. Argue with him but chances are he will laugh at your net raps.
The book is called “There’s a GOD on the MIC” and it lists the top 50 MC’s by his opinion. I will break it down by number. I will only copy the noted strength, noted weakness and any special accolades. If you know Kool Mo then you know he gave rappers report cards, this book does so in number grades (60-100). I will probably mention any noted 100’s. He also had a nick name for each (it will be here)

Subjects: originality, concepets, versatility, vocabulary, substance, flow, flavor, freestyle, vocal presence, live performance, poetic value, body of work, industry work, social work, longevity, lyrics, battle skills

And I better get thank you’s from all you bitches
