The Greatest of All-Time Top R&B/Hip-Hop Artists, Songs and Albums rankings are based on weekly performance on Hot R&B/Hip-Hop Songs [[from its Oct. 20, 1958 inception through Feb. 25, 2017) and Top R&B/Hip-Hop Albums [[from its Jan. 30, 1965 inception through Feb. 25, 2017). Songs and Albums are ranked based on an inverse point system, with weeks at No. 1 earning the greatest value and weeks at lower spots earning the least. Due to changes in chart methodology over the years, eras are weighted differently to account for chart turnover rates over various periods. Artists are ranked based on a formula blending performance, as outlined above, of all their Hot R&B/Hip-Hop Songs and Top R&B/Hip-Hop Albums chart entries.
