R&B/Hip-Hop

The Hot R&B/Hip-Hop Songs chart ranks the most popular R&B and hip hop songs in the United States and is published weekly by Billboard. Rankings are based on a measure of radio airplay, sales data, and streaming activity. The chart had 100 positions but was shortened to 50 positions in October 2012. The chart is used to track the success of popular music songs in urban, or primarily African-American, venues. source: wikipedia
