“Indie” has meant a lot of different things over the years, from the noisy immersion of shoegaze to the minimalism of electro-pop and the shambling romance of garage rock. This playlist is here to capture all of it—or if not all of it, at least the tracks that have helped define indie’s inventiveness and slightly contrarian attitude: a history of people doing it a little differently. Our editors update picks here regularly, so if you hear something you like, add it to your library.
