Adult Pop Airplay

The Adult Pop Airplay (formerly known as Adult Pop Songs and Adult Top 40) chart is published weekly by Billboard magazine and ranks "the most popular adult top 40 as based on radio airplay detections measured by Nielsen Broadcast Data Systems."^[1]

It is a format in which the genre is geared more towards an adult audience who are not into hard rock, hip hop, or adult contemporary fare. The main genres within this format are alternative rock and mainstream pop that is more adult-oriented. It is not to be confused with adult contemporary where rather lesser-known and more ballad-driven songs are played. The current number-one song on the chart is "Birds of a Feather" by Billie Eilish.^[2]

The chart was first published in the March 16, 1996, issue of Billboard; however, historically, the chart's introduction was in October 1995, when it began as a test chart.^[3]

The Adult Top 40 chart was formed following a split of the "Hot Adult Contemporary" chart due to the growing emergence of Adult Top 40 radio stations in the 1990s. These stations played a wider variety of artists and saw a faster turnover of songs compared to traditional adult contemporary radio. Songs by modern rock, dance, and R&B artists were mixed in with acts more closely associated with adult contemporary. According to Billboard, splitting the chart "better reflect[s] the music being played on adult contemporary and adult/top 40 stations."^[3]

The first number-one song on the Adult Top 40, from the test chart of October 7, 1995, was "Kiss from a Rose" by Seal.^[4] The first number-one song on the Adult Top 40, from the published chart of March 16, 1996, was "One Sweet Day" by Mariah Carey and Boyz II Men.^[5]

There are 40 positions on this chart. Songs are ranked based on its total number of spins per week. This is calculated by electronically monitoring Adult Top 40 radio stations across the U.S. 24 hours a day, seven days a week by Nielsen Broadcast Data Systems.

Songs receiving the greatest growth receive a "bullet", although there are tracks that 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 two songs are tied in spins in the same week, the one with the biggest increase that week ranks higher.

In 2016, for the 20th anniversary of the chart, Billboard compiled a ranking of the 50 best-performing songs and artists on the chart over the 20 years. "Smooth" by Santana featuring Rob Thomas was ranked as the #1 song, while Maroon 5 was ranked as the #1 artist.^[10] Listed below are the top 10 songs and the top 10 artists.
