The singer admitted that he feels he needs to reinvent his musical style with each album, as fans become tired of albums quicker since the introduction of online streams and YouTube.
"People get bored. Everything is so accessible that they get sick of things," Bieber told Style magazine.
"A new song gets old quickly, because fans can go on the internet and watch it so many times in a row. You have to be creative fast."
He added: "If I stayed doing the music I did on my last album, they'd get bored. They've already had that. I just have to give more and more."
Bieber recently became the first artist to exceed 800 million views on YouTube after the video for his debut single 'Baby' passed the milestone last month.
