There has n't been a former Alternative Song in # 1 of the Mainstream Top 40 chart for over two-and-a-half-years .
Additionally , it was the number one song on the year-end Chart of 2016 for Hot Rock Songs , which when combined with Ride and Heathens , gave Twenty One Pilots a clean sweep of the top three year-end Hot Rock Songs chart for 2016 . `` Stressed Out '' is the first former Alternative Songs number one to top Mainstream Top 40 in more than two-and-a-half-years , since Lorde 's `` Royals '' in 2013 .
