Artists draw inspiration from a variety of things, and sometimes, it's other artists.
Appearing in a new Beat x Beat webcast produced by Beats by Dre, Coldplay frontman Chris Martin explained the creative process when it came to writing the band's hit song "A Sky Full of Stars," and revealed that there was one popular pop queen whose music really helped spark the idea behind the chart-topping Coldplay track.
And you may be surprised at who it is.
"I'll tell you the truth: I was listening to a lot of Katy Perry," Martin said.
Yep, that California Gurl is partially to thank for that song you can never get out of your head.
