As young people swarmed to see the summer blockbusters, we released our film trailer. No trailer is complete without an unforgettable soundtrack. One that you literally can’t get out of your head. So we looked at our data and saw that Camila Cabello's guilty pleasure “Havana” was about to become the most-streamed song by a female artist, ever. We picked that, and created a horror film trailer, a genre that indexed highest with our young-adult target.
