In addition to album sales, Billboard factors in performance on the Hot 100 singles chart, which incorporates radio airplay, sales and streaming figures, plus artists' touring revenue, Social 50 chart activity and ringtone sales.

Behind Mars at No. 2 is Swift, followed by Timberlake, Rihanna, Macklemore & Ryan Lewis, Pink, Imagine Dragons, One Direction, Cyrus and Maroon 5.
