Powered by a 72 percent increase in on-demand audio streaming, eight of the top 10 albums came from the world of rap or R&B, including Kendrick Lamar’s “DAMN,” Drake’s “More Life” and “24K Magic” by Bruno Mars, according to Nielsen Music’s 2017 year-end report, released on Wednesday. Rap and R&B also dominate the Grammy awards later in January, with rapper Jay-Z and Lamar leading nominations.
