I and Love and You, by the Avett Brothers.
This song is just too damn pretty, even if the “Brooklyn, Brooklyn” line is probably both a symptom and cause of quite a bit of gentrification of some neighborhoods that look a lot more like the Avett Brothers than they did when I lived in New York City, myself an early-ish gentrifier of a block that famously (in a story that I often tell) from cockfighting to French restaurants in six years.
