My town's song is a part in the Nutcracker Suit that I had to play in band over an over 61 times in the song. I don't know why I decided that, but I did!
At first it was the tune to Secrets by OneRepublic, but then it changed to the beginning of Fix You by Coldplay, then I just changed it back to what the default was and played around with some tunes.
Well, I have 5 towns and not sure what each of the tunes are ATM, I recently started playing and haven't payed attention to the town tunes, except for one because someone came to get a villager and said they liked my town tune, so I checked to see which one it was
I know one of my towns has Fireflies by Owl City on it. I didn't make the tune, I found it on google
it's been the same one since i changed it about 2ish years ago. asuna's theme from sword art online (i'm not rly a fan of sao tho i just like asuna and her theme)
