To determine the most popular rock bands of all time, 24/7 Tempo generated an index based on the popularity of a band on streaming service Spotify and Facebook, Ranker user votes as of July 21, 2020, and lifetime performance on the Billboard 200 album charts. Each component of the index was given equal weight.
Popularity on Spotify was based on the number of followers each artist has on the music streaming app, and Facebook popularity was based on the number of “likes” each artist has. User votes came from a list on crowdsourced ranking platform Ranker, which ranks the best rock bands of all time. To be included on our list, a band had to appear on this Ranker list. Billboard 200 performance includes both position and number of weeks an album spent on the chart, which tracks the popularity of albums across all genres.
