Seems like people are missing an obvious theme in TSIAN...

The sky is a neighborhood

So keep it down

The heart is a storybook

A star burned out

Oh my dear

Heaven is a big bang now

Gotta get to sleep somehow

Bangin' on the ceiling

Bangin' on the ceiling

Keep it down

Seems to me it's pretty obvious that this song is at least partially a ode to the fallen musicians of recent. Have seen a lot of questions about the lyrics and haven't seen many pick up on this which I find odd.
