I didn't mean to imply Hikki doesn't use these themes in her songs, but rather that she expresses them to better effect through anecdotal types of lyrics whereas Ayu can explicitly and generally talk about the broader themes, like a philosopher. Haha, I actually do regard Ayu's lyrics as philosophy sometimes. Even songs that exude poppy shallowness on the surface like everywhere nowhere have an interesting lyrical message, but that's neither here nor Hikki
