thankfully you put a question mark in parentheses. I always thought the story was in all the struggle between the heart and the synapse. The Synapse (character?) kind of just dictates the body ignoring the desires of the heart. The Heart wants meaning in life and and so the Heart takes control giving PURPOSE. Interpret it as you wish but THAT is the way I always felt about BTHATS and I have been listening to it since it came out.
Now about the poems. Its a great idea and Casey himself would be proud of you because their songs are sophisticated and poetic.
If you need any other interpretations for songs I can help ya. For example, Flee the Factory. It can be a motto in your life because basically don't be a a damn robot and don't conformist.
good luck with your poems and I will be reading them
