There will be a shuffle medley.
It's a secret every year.
It's up to 24 songs and takes until 11:57pm JP.
Then hologra countdown from there.
Happy New Year!
From there it's a shuffle medley with an unreleased setlist
This is how it went last year.
My guess is symmetry will be sung by the 0th period in regross idol costumes
