What animal crossing song is this?

[Jarrad]

What's the song played in this video?

Also, does anybody know why I can't seem to find any of the ripped OST from AC: Amiibo festival on youtube? I don't have the game, but I imagine that it has a different soundtrack to the other AC games, yet nobody (as far as I know) has really taken interest/notice of the OST.

It's a different version of K.K. chorale.
