What song are villagers singing?

[celesludenberg]

To start off, sorry if this has been asked before! I think it’s really cute how villagers sing in this game. I know sometimes they will sing when you play a song near them. I was wondering if anyone knew what song they are singing when they stand around randomly and just start singing out of nowhere? You know when they’re just standing near the Town Hall or whatever it’s called in this game and just start belting it out? I thought it would be a kk song but can’t place my finger on what it is.

It's just a default song, if there's no music playing on a music player that's been set outside.
