Chris Martin has revealed he was inspired by Katy Perry to write uplifting track Sky Full Of Stars.
The Coldplay frontman - who announced his "conscious uncoupling" from wife Gwyneth Paltrow earlier this year, admitted that the band's latest album Ghost Stories is about heartbreak. But listening to pop princess Katy helped him write the record's more upbeat track.
Chris revealed in a new video for Beats by Dre: "I'll tell you the truth - I was listening to a lot of Katy Perry. A lot of her songs have the same chord sequence the whole time. Your body feels comfortable with them and then the melody is changing on top so there's a groove you really get into."
He went on: "Then I realised all these other people that have done that. Nirvana being a classic example - Smells Like Teen Spirit is the same chord sequence basically the whole time. There's a simplicity to that. I needed to find a sequence that I could play for ages and ages and ages.
"Some people turn their nose up at [it], but then you go and see an EDM thing and people are so together and having the best time," said the singer. "So I was like 'F*** it, I love that stuff, I want us to have a song that comes from that world'."
Chris admitted that Sky Full Of Stars is a glimmer of light relief in a very emotional album.
The singer said: "Ghost Stories is probably an album about heartbreak, but it's not saying that something is broken so you should just give up. It's saying something is broken so let's fix it and make it better than it was before."
