I'm of the opinion that being in a group should have no bearing on your ability to be considered on lists like this.
And I absolutely believe Prodigy should be considered. If you talked to me around '95/'96 I would've told you Prodigy is the best rapper on the planet, no question.
I do not believe being in a group should disqualify 3K from being on a list like this. I believe that him not having solo projects should disqualify him from being on this list. Ghostface is a very prominent member of a group but I believe he deserves to be on the list because he has an extensive and impressive solo catalog.
