His most replayed work. I'm sure you've heard it, but many don't know it's Chopin. If you realize that now, it may be a chance for some rewarding Spotify exploration...
I've always wished John Williams would just include this piece straight up in a Star Wars movie. Both to acknowledge the inspiration and just because it would be perfect sad, brooding music as the camera panned across across a smashed rebel base or whatever.
Don't skip the rest of his nocturnes either. Especially Op 9 no 1, Op 55 no 1 (I'm practicing that one now), Op 62... You know what, just go listen to all of them.
