Bruno Mars found it ''daunting'' working on his new album.

The 31-year-old singer songwriter has admitted he was apprehensive about releasing '24K Magic', which is the first album he has released in four years, because 'Uptown Funk' was ''the biggest song'' he had ever worked on and released.

Speaking on '60 Minutes', the dark-haired hunk said: ''This album, it was daunting, because coming off of 'Uptown Funk' was like the biggest song I've ever been a part of. And then you're like, alright, now what are you gonna do?''

The 'Just The Way You Are' hitmaker has admitted he ''really cares'' about what his fans think of his music and he is ''working hard'' to be a successful artist.

He explained: ''I just really care about what people see. I want them to know that I'm working hard for this. The artists that I look up to like, you know, Michael, Prince, James Brown. You watch them and you understand that they're paying attention to the details of their art. And they care so much about what they're wearing, about how they're moving, about how they're making the audience feel. They're not phoning it in. They're going up there to murder anybody that performs after them or performs before them. That's what I've watched my whole life and admired.''

The Hawaiian-born star has admitted he also wants people to think of him, his home country, as well as ''palm trees and magical islands'' when they listen to his tracks.

He said: ''These are my people, and this is my culture, and I want to represent them. I want people to think of Hawaii and think of palm trees and magical islands and Bruno Mars.''

And Mars believes if the audience aren't ''freaking out'' and reacting positively to his performance there's something wrong.

He said: ''And if you wasn't hitting those notes and the audience wasn't freaking out, then you weren't doing it right.''
