In an interview with Digital Spy, when asked about the meaning of the song (and the claim that it is happier than some of her previous work), Goulding replied:

It’s about letting go. As opposed to all the sad and depressing things I write about, I decided to write something about the joining together of people in some kind of euphoric state – be it at a festival, at a show or in a club. I wanted a song that would reach out to people of every background and every enjoyment, whether you enjoy a natural high, taking drugs, drinking or whatever. Because I’m essentially a pop artist I wanted to write a song that everyone can relate to.
