The 2-1 is not an indicator of Season but just the weird way they seperated the episodes (they always do with game caterers and everything else on the full moon channel). Also, I canβt really give you much singing with this show, but 2-2 and 3-1 are music quiz episodes and there will be a lot of performing and fanboying of other songs with occasional singing haha, itβs my favorite part of this show (the next one is a quiz and the last one an extraordinary game of basketball hehe)
