Yeah, I almost feel like the new myu had a script written out and then they looked to see what they could make songs, while the old myus feel like they had an outline that was mostly songs as the major points, and then they looked at how they could write scenes to make the songs work.
I think that’s why a lot the the new myu’s strongest songs are villain songs– that’s the easiest way to bring their motivations to the audience, and there’s no waffling over if they really want a song there.
