More footage of Squid Sister amiibo functionality?

Found this tweet showing footage of a display advertising the Callie amiibo. It shows Callie performing [whatever her solo song is called] in parts of various stages. The footage appears to be rendered with in-game assets, so it's possible that this an alternate way of listening to the music in game. What are your thoughts on this?

That would be neat! Perhaps it would it be a way to hear them preforming while you're playing? If not, it's probably her preforming on different stages for aesthetic.
I'm still hoping that they add a way to play the stages at night on the amiibos with the fact they're no longer doing splatfests after the next one.
