It's no wonder Sky Full of Stars is one of Coldplay's catchiest ever songs.
Frontman of the chart-topping Brit band Chris Martin has admitted that the song was inspired by none other than Roar hit maker Katy Perry.
In this behind-the-scenes video, Martin explains: "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 the melody is changing on top so there's like a groove that you really get into and then also you're kept interested."
He added that the song has its roots in EDM, saying he showed Avicii the song and asked for help.
Martin went on to describe the song as the "most important" the band had ever had, lyrically. He said: "Every time I sing it I'm like 'Yeah, that's how I want to live my life'".
