Dave Grohl remembers hearing Lorde sing for the first time because it stood out amongst the "stripper pop".
"I was driving," the Foo Fighters frontman told Rolling Stone magazine.
"My two daughters, Violet and Harper, who are eight and five years old, started singing along. I was so happy and relieved that my two girls were singing a popular song on the radio that had some substance and depth, which I considered to be healthy for them as kids. I know that sounds kind of parent-ish.
"When I first heard Royals it was sandwiched between all of that other stripper pop," he said.
"I was so f****** relieved. I thought, 'Hey, this might be another revolution.' When I met her I said, 'When I first heard your song on the radio and my kids sang along I felt like there was hope for my kids to grow up in an environment which is more than just superficial.'"
