There's not a such thing as conversational flow,just a cute term I guess somebody decided to make up to erroneously credit Nas with something? I've already cited multiple rappers that predate Nas,that had a style that came off more as if they were talking to the listener than rapping at them,and many of them have differnt flows,Maybe Kool Mo Dee is ignorant on the topic and never heard of the likes of Scarface and Ice Cube etc. That style is really not all that unique and there is certainly not one flow that can be used to get that style off. You can't call that a flow when theres not one specefic flow to use for your style to be that of a conversationalist,as I have proven. Nas to me isn't even the best example of that style,so for him to credit Nas with creating that is laughable. Jay is actually by faaaar much better at that conversational style than Nas,he had already surpassed Nas in terms of that style by his first album lol. RD is a much better use of that style than Illmatic,I suggest some of you go back and listen to both.
