Eternal Encore

Seem the concert is stuck on one song, she comes in and only sings Eternal Encore. Which if I remember my PSU edition and the early alpha and beta test correctly is supposed to be the rare hidden encore song if enough people request encore in area chat.

They have scheduled it to be this way:

So the encore being the only song right now is intentional? That seems weird, and a sure way to make what is supposed to be a rare event into trope, and boring.
