The summer before my senior year of college, I went through a music transformation. All through college I had been consumed by EDM. That’s what I listened to while sprawled on the floor surrounded by textbooks. But in 2011, I began to fall for a hipster, and I also began to listen to her music. These were separate changes, but they certainly converged—and maybe became intertwined.

The Lumineers had just stepped onto the stage. Pandora stilled trumped Spotify. We all kept iTunes libraries. I regularly converted YouTube videos into MP3s. And she sat behind me in biology class.
