Three boss songs also could also be unlocked through this event. Clearing all charts in Normal mode of the 2ndMix mode would unlock "TRIP MACHINE EVOLUTION" on Extra Stage, while clearing all charts in Hard mode would unlock "PARANOiA Revolution".

The 1-life battery in Encore Extra Stage was uniquely made to fail the player if they get GREAT or lower (instead of GOOD or lower).
