When Kitsch first dropped there were so many allogations that Liz was being mistreated, and many (including myself which I feel very ashamed of now) theorised it might've been a punishment.
I just watched the total distributions for all IVE songs. The amount of lines she gets in I'VE IVE is insane.
I mean, look how many lines she got in Next Page
I didn't watch the full distribution but it seems she got a lot of lines from adlibs. But like, she still got very good lines in the rest of the song looking at a ccl sheet without said adlibs.
So now my two theories are basically that:
1. The less sinister: because of how many lines Liz got in the other tracks, Starship balanced it out with Kitsch. Not the most fair, they could've just made good distributions for all the songs to start with, especially since Kitsch is fully promoted. But like if she was singing that much in the other songs it might make senses
2. The more sinister: it was used as a promotional tactic. Get everyone raging at the poor distribution, justice for Liz all that then boom girly gets most lines in the title track including hard belting notes, and many 1sts and 2nds for the rest of the album. Kinda genius ngl, since I wouldn't be surprised if companies are well aware of the outrage distributions can cause.... But like my girl Liz doesn't deserve to be used as a marketting stategy!
Anyways. There we go
