Rhythmic Top 40

The Rhythmic chart (also called Rhythmic Songs, and previously named Rhythmic Airplay, Rhythmic Top 40 and CHR/Rhythmic) is an airplay chart published weekly by Billboard magazine.

The chart tracks and measures the airplay of songs played on rhythmic radio stations, whose playlist includes mostly hit-driven R&B/hip-hop, rhythmic pop, and some dance tracks. Arbitron sometimes refers to the format as rhythmic contemporary hit radio.

Billboard magazine first took notice of the newly emerged genre on February 28, 1987, when it launched the first crossover chart, Hot Crossover 30. It originally consisted of thirty titles and was based on reporting by eighteen stations, five of which were considered as pure rhythmic. The chart featured a mix of urban contemporary, top 40 and dance hits. In September 1989, Billboard split the Hot Crossover 30 chart in two: Top 40/Dance and Top 40/Rock, the latter of which focused on rock titles which crossed over. By December 1990, Billboard eliminated the chart because more top 40 and R&B stations were becoming identical with the rhythmic-heavy playlist being played at the crossover stations at the time.

Billboard revived the chart in October 1992 as Top 40/Rhythm-Crossover (along with Mainstream Top 40), with the first number one being "End of the Road" by Boyz II Men. On June 25, 1997, it was renamed to Rhythmic Top 40 as a way to distinguish stations that continued to play a broad based rhythmic mix from those whose mix leaned heavily toward R&B and hip-hop. It was changed to Rhythmic Airplay in the February 7, 2004, issue and shortened to Rhythmic on July 12, 2008.

The current number-one song on the Rhythmic chart for the week ending March 11, 2017, is "Bad and Boujee" by Migos featuring Lil Uzi Vert.
