1. According to a 2018 Nielsen Music report, rock music accounted for 17% of total music consumption in the United States. This means that out of every 100 songs played, 17 of them were rock songs.
2. A 2017 study by the International Federation of the Phonographic Industry (IFPI) found that 21.5% of global music revenue came from rock music, making it the second most popular genre after pop.
