For me I look at a group like Queen or AC/DC or the Beastie Boys. There was melody within what they did. There was a certain style with what they did. I think it is coming back.

I was probably five years old or four years and I would listen to "White Christmas," and I just thought it was the most beautiful thing ever. The musicianship and his voice and the melody of that song; it's almost like I wish it wasn't a Christmas song because I wish that you were allowed to listen to it all year.

On social media and [in person] I hear stories of how a song like "Home" helps. Whether it's a guy overseas coping with missing his family or something deeper and terribly dramatic. Somebody once told me that ["Home"] is the song they listen to when they go to the cemetery to visit their child that passed away. It gives them hope. At the end of the day, that's all what I want to offer people.

This is why I wanted to be different and why I wanted to have power and fame and money: because I wanted to be attractive to the opposite sex. I'd be lying to you if I didn't say that was a big part of it

I realize I have made a lot of mistakes and done things wrong. I've done things I wish I could have done in another way. I didn't come in with the same kind of desperation that I may have had on the first or second record. I didn't come in thinking, 'Oh God, please. I hope this does well because I have nothing else and I worked so hard at this.'

I see that I have been engaged to Emily [Blunt] without ever asking her. The big question I had was, do you think I would ask her to marry me through 'Hello' magazine? Would I do something like that? Would she allow that to happen? It is completely ridiculous.

I brought in producer Johan Carlsson [Ariana Grande, One Direction, Flo Rida] and asked, "Can you make this better?" And he did.
