A few years ago I crossed the Brooklyn Bridge into Chinatown with In the Mood for Love in my headphones. For a few minutes the city stopped being a place and became a film — every passing face a frame, every red awning lit like a set.

A flâneur is a nineteenth-century French word for the one who wanders the city not to arrive, but to feel it — the stroller, the watcher, the one who reads the street like a page. The city was their gallery; the crowd, their poem.

Flâneur is an app for that kind of walking. As you move, it plays music rooted in the cultural and atmospheric identity of each neighborhood — not a shuffle, but the sound that belongs to where you’re standing.
