It was the Saturday after Christmas. Snow fell outside, but inside, 16-year-old Mia sat cross-legged on her carpet, a bowl of popcorn in her lap, watching the VH1 Top 20 Video Countdown —the year-end special. Host Jim Shearer was hyped, his signature energy bouncing off the screen.

She cringed now, but in July? She’d danced to this in her room with a hairbrush microphone, pretending she wasn’t terrified of starting high school in the fall.

She labeled it with a sharpie:

The countdown began.

December 26, 2009. A basement bedroom in a suburban house. Posters of Lady Gaga, The Black Eyed Peas, and Kings of Leon on the walls. A clunky desktop computer with iTunes open. A TV tuned to VH1.

Jim Shearer held up a sparkly disco ball. “Your #1 video of 2009!”

Alicia’s voice filled the room. Mia had never been to New York, but this song made her believe she could go anywhere. Concrete jungle, green lights, dreams all that. She closed her eyes and imagined her future self—older, cooler, living some big city life. 2009 Mia had no idea what was coming. But this song felt like a promise.
