Hot R&B/Hip-Hop Songs
Hot R&B/Hip-Hop Songs, is a chart released weekly by Billboard in the United States.

The chart, initiated in 1942, is used to track the success of popular music songs in urban, or primarily African American, venues. Dominated over the years at various times by jazz, rhythm and blues, rock and roll, doo-wop, soul, and funk, it is today dominated by contemporary R&B and hip hop. It lists the most popular R&B and hip hop titles as follows:

Between 1948 and 1955, there were separate charts published for Best Sellers and Juke Box plays, and in 1955 a third chart was added, the Jockeys chart based on radio airplay. These three charts were consolidated into a single R&B chart in October 1958.

From November 30, 1963, to January 23, 1965, there was no Billboard R&B singles charts. The chart was discontinued in late 1963 when Billboard determined it unnecessary because that there was so much crossover of titles between the R&B and pop charts in the light of the rise of Motown. The chart was reinstated in early 1965 when differences in musical tastes of the two audiences, caused in part by the British Invasion in 1964, were deemed sufficient to revive it.

On December 11, 1999, Billboard modified the chart's title to Hot R&B/Hip-Hop Singles & Tracks, and changed it again in 2005 to Hot R&B/Hip-Hop Songs. In 2009, the chart was again modified to its current title, R&B/Hip-Hop Songs.

Bubbling Under R&B/Hip-Hop Singles
The Bubbling Under R&B/Hip-Hop Singles is a chart composed of 25 positions that represent songs that are making progress to chart on the main R&B/hip-hop chart. Many times, singles halt their progress at this chart and never debut on the Hot R&B/Hip-Hop Songs chart. The Bubbling Under R&B/Hip-Hop Singles chart can also be seen as a 25 position addendum to the chart, but the chart only represents the 25 songs below position #100 that have not yet appeared on the Hot R&B/Hip-Hop Songs chart.

Hot R&B/Hip-Hop Airplay
The Hot R&B/Hip-Hop Airplay chart is the airplay component chart of the Billboard Hot R&B/Hip-Hop Singles & Tracks chart. It is not the R&B subset of The Hot 100 Airplay, but rather a separate panel of R&B stations in urban markets used for the R&B/Hip-Hop chart. It is also used in sister publication R&R, which lists the chart as Urban National Airplay.

Janet Jackson made history in 1993 when her single "That's the Way Love Goes" became the first (and at present time the only) song in history to enter the airplay chart at #1.

Chart criteria
There are forty positions on this chart and it is solely based on radio airplay. Hot R&B/Hip-Hop Airplay is a component chart of the Hot R&B/Hip-Hop Singles & Tracks chart. 77 R&B/Hip-Hop radio stations are electronically monitored 24 hours a day, seven days a week by Nielsen Broadcast Data Systems. Songs are ranked by a calculation of the total number of spins per week with its "audience impression", which is based upon exact times of airplay and each station's Arbitron listener data.

Songs receiving the greatest growth will receive a "bullet", although there are tracks that will also get bullets if the loss in detections doesn't exceed the percentage of downtime from a monitored station. "Airpower" awards are issued to songs that appear on the top 20 of both the airplay and audience chart for the first time, while the "greatest gainer" award is given to song with the largest increase in detections. A song with six or more spins in its first week is awarded an "airplay add". If a song is tied for the most spins in the same week, the one with the biggest increase that previous week will rank higher, but if both songs show the same amount of spins regardless of detection the song that is being played at more stations is ranked higher. Songs that fall below the top 20 and have been on the chart after 26 weeks are removed and go to recurrent status.

Hot R&B/Hip-Hop Singles Sales
The Hot R&B/Hip-Hop Singles Sales chart is the sales component chart of Hot R&B/Hip-Hop Songs. It is not the R&B subset of The Hot 100 Singles Sales, but rather a separate panel of sales of commercial singles in the urban market. Due to the decline of standard commercial CD singles for the urban market, the chart is most often filled with the sales of 12-inch maxi singles, a format popular in urban markets.

Rhythmic
The Rhythmic Airplay Chart (often also called Rhythmic Top 40 or CHR/Rhythmic chart) is an airplay chart that is featured weekly in Billboard Magazine. The chart tracks and measures the airplay of songs played on Rhythmic 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.

History
Billboard magazine first took notice of the newly emerged genre on February 15, 1987, when it launched the first crossover chart. The first number one on that chart was "Looking for a New Love" by Jody Watley and it originally consisted of thirty titles and eighteen stations reporting to the panel. But by December 1990 Billboard eliminated the chart because more top 40 and R&B stations were becoming identical with the rhythmic-heavy playlist that were also being played at the crossover stations at the time.

Billboard would later revive the chart again in October 1992 as the Top 40 rhythm/crossover chart, with "End of the Road" by Boyz II Men as the first number one on the revived chart. On June 25, 1997, it was renamed the Rhythmic Top 40 chart as a way to distinguish stations that continue to play a broad based rhythmic mix from those whose mix leaned heavily toward R&B and hip-hop.

The current number one on the Rhythmic chart for the week ending May 28, 2011 is "E.T." by Katy Perry featuring Kayne West.

Hot Rap Songs
Rap Songs (formerly known as Hot Rap Tracks and Hot Rap Singles) is a chart released weekly by Billboard in the United States. It lists the 25 most popular hip-hop/rap songs, calculated weekly by airplay on rhythmic and urban radio stations and sales in hip hop-focused or exclusive markets. From 1989 through 2001, it was based on how much the single sold in that given week. The most weeks at number one was "Hot Boyz" by Missy Elliott, a single that was number one for 16 weeks from December 1999 to March 2000.
