Worcester Magazine David Saint Fleur gets excited talking about “Heartbreak Anthem,” the new song by the Swedish DJ duo Galantis, French DJ David Guetta and British girl group Little Mix, for which he was a writer and producer. “It's on fire,” says Saint Fleur, a Worcester native and Burncoat High School graduate who currently works as a music producer and an A&R executive for Warner Music Group. “It's breaking every record … It's never done less than a million (streams) a day since it came out.” His enthusiasm is understandable, seeing as the song is currently exploding on the Billboard dance and electronic music charts and on streaming services, but it would also be understandable if he were a little jaded. After all, he's had hits and worked with big names before, including Bebe Rexha, Dolly Parton and 24kGoldn. But no, his excitement and enthusiasm for the song and the people he worked with to put it together is evident the moment he starts speaking.
