3. “Sorry”- Justin Bieber
Another artist who took a big step out this year and challenged themselves was Justin Bieber. Shedding the teen image for good, Bieber stepped out musically venturing into EDM with his hit “Sorry” creating a bridge between pop and EDM creating a smooth marketable sound to be enjoyed in and out the club. Bieber has also displayed a great deal of maturity in the delivery of vocals on the track.
