Adult Alternative Songs, also known as Triple A, is a record chart currently published by Billboard that ranks the most popular songs on adult album alternative radio stations. The 30-position chart is formulated based on each song's weekly radio spins, as measured by Nielsen Broadcast Data Systems. Initially published by Billboard sister publication Radio & Records as the Adult Alternative Top 30 Tracks chart, it debuted on the week of January 20, 1996. For much of its early existence Adult Alternative Songs was compiled using Mediabase data, until Radio & Records was acquired by Billboard parent company VNU Media and Nielsen Broadcast Data Systems replaced Mediabase in monitoring airplay for the chart.
Billboard debuted their Triple A chart in the issue dated July 5, 2008 through their Billboard.biz website, appropriating the same airplay data as Radio & Records.Radio & Records later closed in June 2009, leaving Billboard as the sole publisher of the chart. In February 2014, the chart's reporting panel was expanded from 23 to 32 stations, including non-commercial reporters for the first time. The current number-one single, as of the chart for the week ending July 19, 2014, is "Stay with Me" by Sam Smith.
