Song Meaning
The provided lyrics for "考えてきたこと (WHAT I'VE BEEN THINKING ABOUT)" are explicitly marked as "[Instrumental]". This immediately tells us the piece communicates its core message through sound alone, rather than any spoken or sung words. There is no textual narrative or emotional texture to dissect here.
Without any lyrical content, the listener is left to infer "what I've been thinking about" purely from the musical arrangement. This absence of words means we cannot identify specific images, phrases, or contrasts within the lyrical text itself. The song's emotional impact must stem entirely from its sonic landscape.
Consequently, any analysis of craft elements like word choice, repetition, or metaphor is impossible based solely on the provided lyrical input. The effectiveness of this piece, from a textual perspective, lies in its deliberate silence. It invites a deeply personal, unguided interpretation, allowing the music to speak for itself without the constraints of language.
