Nas is the best rapper still on this planet... lyricism, flow, etc.... but hes not DOOM. no one is and ever was. its hard to compare anyone to him because of what hes done not only as DOOM, but also and King Geedorah, Madvillian, DangerDOOM etc. etc. This is my opinion of course but the supervillian is a model for where modern day hip hoppers should be heading
etc, doom, supervillian, dangerdoom, madvillian
