Bubbling Under R&B/Hip-Hop Singles
From Wikipedia, the free encyclopedia
The Bubbling Under R&B/Hip-Hop Singles is a chart released weekly by Billboard in the United States. It is comprised of 25 positions that represent songs that are making progress to chart on the main R&B/hip-hop chart, the Hot R&B/Hip-Hop Singles & Tracks. Many times, singles halt their progress at this chart and never debut on the Hot R&B/Hip-Hop Singles & Tracks chart.
The Bubbling Under R&B/Hip-Hop Singles chart can also be seen as a 25 position addenum to the Hot R&B/Hip-Hop Singles & Tracks chart, but it should be noted that the chart only represent the 25 songs below position #100 which have not yet appeared on the Hot R&B/Hip-Hop Singles chart. If a song were to be ranked at #99 but then declined the following week to a position that is comparable to position #105, it would not be eligible for the Bubbling Under R&B/Hip-Hop Singles chart because it already appeared on the Hot R&B/Hip-Hop Singles & Tracks chart.
