Hot Christian Songs (also known as National Christian Audience) is a Billboard chart published weekly by Billboard magazine in the United States.
From its inception in June 2003 through November 2013, the Christian Songs chart ranked the top songs by calculating overall audience impressions of songs played on contemporary Christian music radio stations. Sales from digital downloads were not factored in. With the Billboard issue dated December 7, 2013, the Christian Songs chart began utilizing the same methodology used for the Hot 100 chart to compile its rankings; that is, measuring the airplay of Christian songs across all radio formats, while incorporating data from digital sales and streaming activity.
