In determining these rankings, the Billboard and Vibe editorial teams opted first to limit the rap arena to North America. So for example, as estimable as his career is, British rapper Slick Rick isn't on this list. We also opted not to include the significant contributions of reggaetón and dancehall MCs on this list, just to keep our pool of nominees a little more focused.
From there, the teams took into account the following criteria, not in any particular order: body of work/achievements (charted singles/albums, gold/platinum certifications), cultural impact/influence (how the artist's work fostered the genre's evolution), longevity (years at the mic), lyrics (storytelling skills) and flow (vocal prowess).
As is well known, GOAT and similar best-of lists always draw their share of criticism and praise from industry pundits and the public alike. So it took a lot of deliberation and deep discussion to reason our way to what we believe is a well-thought-out, authentic list
