The offshoot Hot Alternative Songs and Hot Hard Rock Songs charts premiere.

Billboard has revamped the multi-metric Hot Rock Songs chart as the newly-named Hot Rock & Alternative Songs survey.

Concurrently, two multi-metric genre charts debut: Hot Alternative Songs and Hot Hard Rock Songs.

The change from Hot Rock Songs to Hot Rock & Alternative Songs reflects the rise of artists making music that is often considered alternative, but does not fit within the commonly held boundaries of rock. This subset of music has been noticeable not only on Billboard‘s Alternative Songs airplay chart, which tracks airplay on radio stations playing the alternative format, but also on the all-genre Billboard Hot 100 chart, via such artists as Powfu, Billie Eilish and Benee.

The 50-position Hot Rock & Alternative Songs chart, which will continue to rank songs via a blend of streaming, radio airplay and sales data as tracked by Nielsen Music/MRC Data (the same methodology that powers the Hot 100), will house songs deemed either rock or alternative, or both, as it expands beyond a listing of core rock titles, including those with an alternative bent, to include songs considered a hybrid of pop and alternative, rap and alternative and more.

Powfu’s breakthrough hit “Death Bed,” featuring Beabadoobee, rules the first iteration of the newly christened Hot Rock & Alternative Songs chart dated June 13.
