How Having the Song of the Summer Can Ruin Your Career

By now, you’ve undoubtedly heard of rapper Iggy Azalea, the 25-year-old Australian blonde with the face of a model and a disproportionate derrière that she shakes proudly in music videos and jokes she can’t squeeze into a normal-size dress. But the real reason you know Azalea is that her song Fancy—with its brilliantly inane chorus, “I’m so fancy/You already know/I’m in the fast lane/From L.A. to Tokyo”—was America’s No. 1 hit for seven weeks last year. It outperformed John Legend’s All of Me and Pharrell Williams’s Happy, ultimately becoming the Song of Summer for 2014.

Summer has long been a brisk season for the music business, and it has often featured an unofficial anthem, but the Song of Summer is a recent phenomenon. Five years ago, Billboard turned the coronation of a single hit into an event when it created its Songs of Summer chart, tracking releases from Memorial Day to Labor Day. The magazine also pored over its historical data and found the most popular jams of the previous 25 summers, from Tears for Fears’ Shout in 1985 to Rihanna’s Umbrella in 2007 and Katy Perry’s I Kissed a Girl in 2008.
