Another incredible interview. Check this out!
Furthermore, I'd like to touch on the poetry and rhythm of a few of the songs. Know how in poetry, the rhythm of a poem can symbolize what the poem is about? (A poem about a train having a "chugachuga" rhythm for example)
YLIAL is very linear and repetitive to represent the typical socially expected life the song is about. (Not attributing any genius to the song, simply an observation.)
Next comes I Love You Too, Death. I love this song. It's all about death and has a positive message. The song starts off pretty...scary actually. Scary is the word I'd use to describe it. Then, as the lyrics and message transition to a positive outlook on death, the song becomes more upbeat, or even happy.
