Songwriter Jason Boyd, known as Poo Bear, has been working with Canadian sensation Justin Bieber on his highly anticipated fourth studio album, which is due to be released on November 13. 

During a new interview with the Rolling Stone, Poo Bear confessed that this is easily the star's best record and would say that it's Bieber's equivalent to Michael Jackson's iconic offering, 'Thriller'. He has also been working with Bieber since 2013 so has seen him through very tough times:

"It was a trying time but we made it through, and he definitely matured, which leads us to this new album. It's incredible. And if I had to compare it to something, not the sound of it but the impact and amount of songs that are undeniable, I would have to compare it to 'Thriller'."

"We recorded a lot of songs, 103 songs, over the past couple of years... just making sure that everything is in the direction we want to stay in, which is uplifting music, real-world music. This is so the world can understand: 'If you're going through what I went through, this is what I did to get through my problems.' Justin always wanted to be that light, that example. And we really hit it with this album."

He added: "You'll get to hear him really get intimate with things that he went through in his life in the last couple of years, so that people can understand him, kind of like with 'Human Nature'. Big, powerful records that everyone can listen to. This album is so inspirational."
