Billboard Rock Charts Billboard’s rock and alternative charts track the ever-evolving, oft-debated, subgenre-laden category of popular music that originated in the mid-1900s as an amalgamation of sounds from rockabilly to the blues, folk to R&B and jazz to country. Nowadays, Billboard distills the genres’ many subsets into rock, alternative and hard rock subcategories, via album and song charts measuring streaming, radio airplay and/or sales data, as provided to Billboard by Luminate. The combined Top Rock & Alternative Albums and Hot Rock & Alternative Songs charts reflect the top titles encompassing rock and/or alternative and music that also traverses alternative pop, alternative dance and alternative R&B. Billboard also publishes the radio-focused Alternative Airplay, Mainstream Rock Airplay and Adult Alternative Airplay rankings, which track plays at those individual formats, as well as the Rock & Alternative Airplay list that merges all three into one audience-based tally. Top performers on the rankings in the 2020s include Zach Bryan, Coldplay, Billie Eilish, Fall Out Boy, Imagine Dragons, Noah Kahan, Linkin Park, John Mayer, Panic! At the Disco, Shinedown and Twenty One Pilots.
