I think i just realized, "Raise Up Your Bat" was supposed to have two vocalists. a little bit. maybe, kinda, who knows.

IT was something i figured while listening to vocal covers, on the lyrics the part "Because I'm with you in the dark With your heart as my mark Which shall guide you the way, through the waves" the "through the waves" often sounds kinda weird IMO, the vocalist ways need to sing this faster then rest of the line, so it fits. this wouldn't happen if a second vocalist started singign the "through the waves" part before the other finished the "Which shall guide you the way"

one could argue that its supposed to be like that cus' it also happens on the Lightners live in-game, but again, Kris can't talk much which would make Ralsei deal with it by himself, and he was adlibing the whole song anyways.

the song is a Swing Rhythm so maybe it was also supposed that the Vocalist also sang half of the song each instead of just one?

I'm prolly wrong anyway
