City tunes have always been one of the best ways to personalize your Animal Crossing city. In New Horizons, it is no longer an air of "city", of course. They are island tunes now. But luckily, the interface is pretty much the same, so you can use your old favorites in your new home.
NookNet has a wonderful Island Tune Creator that works just like the in-game interface, so you can browse through songs others have created or create your own. Translating a song into such a simplified format is incredibly difficult, so unfortunately a lot of songs aren't as recognizable as their authors want them to be.
We've scoured hundreds of bits of the city to bring you this list of the best bits on the island.
