His latest is 'Treat You Better', the first single from his new album, 'Illuminate', which has gone to No 1 in 36 countries. His deep lyrics and powerful sound have got him on Forbes magazine's '30 under 30' list in 2016, he performed at the 2016 People's Choice Awards, where he won Breakthrough Artist, and he's twice been on TIME magazine's list of 30 Most Influential Teens to boot. What were you doing when you were 18?
