Tally Hall's song "Ruler of Everything" is a "nothing matters and that's terrifying" song. Contrasting that song, though, earlier in the album is "Spring and a Storm", imo a "nothing matters and that's okay and special" song. It ends with:

Create until nothing is left to create

And the Universe bursts with an overworked sigh

Then pretend to, pretend to recrown the creation

And sing the same thing 'til the clouds start to cry

And then over and over and over again

And then over and over and-- never again...

In my opinion, a commentary on how everything has already been done and it's all recycled, but it's special because we're here now, and eventually, on a personal and a universal level, there'll be a last time.
