Hmm maybe it was intentional...the final product sounds nice so I don't really mind
It actually sounds better than the chorus of the Kinki song so I guess it improved
Maybe she could find some new composers but hey what if she ends up picking the recent DAI's composer who makes interesting verses but some of the most horrible chorus I've ever listened to (talking about their latest release Need Your Love)? That would be even worse, so I don't really think we need to complain in that part.
