Boom Clap was released as the first single from the
soundtrack album of
The Fault in Our Stars
It is one of the theme songs for the movie.
The song was written during writing sessions for XCX's debut album, True Romance.
It was offered to Hilary Duff
for her new album, but she declined.
Charli said about it: "My number one project as a songwriter is to write for Hilary Duff, so when I heard
about this, I was like, 'f---k! Are you serious?! This is my 'in! I'm going to make a Hilary Duff album!'
So we sent over 'Boom Clap', but they came back and were like, 'this isn't cool enough for Hilary.
"I was like, crushed, I thought I was a cool writer, but maybe I'm not. Hilary didn't want my song. What a life-ruiner."
Charli explained the song: "Being totally immersed in passion and feeling really safe and really alone with that person...
And while the song itself is very euphoric and enthusiastic
about romance… it's about wanting to fall in love, but there's this hint of sadness in that, which I like."
The accompanying music video for Boom Clap, directed by Sing J. Lee, was filmed
in Amsterdam and premiered on June 2nd, 2014.
The singer explores the same spots that were featured in the movie.
