Rock Songs (chart)

Hot Rock Songs is a record chart published by Billboard magazine. From its debut on June 20, 2009, through October 13, 2012, the chart ranked the airplay of songs across alternative, mainstream rock, and triple A radio stations in the United States. However, since the chart dated October 20, 2012, the Hot Rock Songs chart has followed the methodology of the Billboard Hot 100 by incorporating digital download sales, streaming data, and radio airplay of rock songs over all formats. Before that date the chart was ranked by overall audience impressions (the approximate number of audience impressions made for each play, as determined by BDS data cross-referenced with Arbitron listener information).

Since its introduction, 46 singles have reached the number-one position on the Rock Songs chart. Twenty One Pilots, Foo Fighters and Linkin Park have been the most successful groups, with each having three singles to top the chart. Twenty One Pilots' song "Heathens" is the longest running number-one single, having spent a total of 30 consecutive weeks atop the chart. Twenty One Pilots have also spent the longest time atop the chart, as their three number-one singles have spent a combined 62 weeks at the summit. Out of the 43 singles that hit the number-one position, 11 singles spent two separate runs atop the chart. Coldplay's "A Sky Full of Stars" is the only single to have returned to the top position for three distinct runs. Thirty artists have recorded number-one singles. The first number-one single on the chart was Green Day's "Know Your Enemy", which led the chart's debut week.
