Puyo Puyo (Genesis) (gamerip) (1992)

Hold up!

What the heck is Rejection of Puyo Puyo? Is it unused? If so, why isn't it labeled as 'Unused Track'?
It is unused. It's just listed as that on the sound test, though I guess also labeling it as an unused track would specifiy it's significance compared to the other music tracks.
I'll ask the same question without the chicken or egg.what really came first? Robotniks? Kirby's?
Or puyo puyos?
