This isn't a song that I immediately became addicted too but it's grown on me over the summer.
I saw an earlier live performance by Charlie XCX and (not to beat around the bush) it was terrible so I kind of gave up on her but she seems to have redeemed herself somewhat in my books with this track.
Boom Clap was also on the soundtrack 'The Fault In Our Stars'. I haven't actually seen it yet but I've been told it's pretty good.
Have you seen 'The Fault In Our Stars'? What did you think of the movie?
