Who Was The Biggest Artist In 2015?
Entering at No. 10 is The Weeknd, who released his second studio album, "Beauty Behind The Madness", last year. The singer managed to claim the title of first male artist to top Billboard's Hot 100, Album Top 200 and Artist 100 all at the same time. And in 2016 it doesn't look like he's slowing down, as he heads out on tour supporting Rihanna on her European stadium tour.
