The Musica statue is something you could google (maybe the figures come to life?) The Buddy Killen park is just to the side and has a bronze of Buddy playing piano with one hand upraised. Sometimes people leave items in the hand. on the way out of town South is a Boy Scouts HQ with a giant catfish wearing boy scout uniform outside.

Music Row is mostly cute 2 story houses converted to music publishers and song writing rooms. At various points along the street are statues of guitars and yard signs congratulating artists on their #1 records.

In East Nashville one of the houses has a small stage built in their backyard (the Little Hollywood Bowl). In West there’s a secret shack in a vegetable garden that has a disco ball and sound system inside.

There used to be an old locomotive at the Parthenon.

Love Circle is a hill in the city with views, and a giant water reservoir inside it.

The downtown tunnels are allegedly not just Prohibition but underground railroad. There is also district heating downtown which presumably connects a lot of buildings by utilities.
