Meaning of "Great Days for the Passenger Element" by Autolux

The lyrics of "Great Days for the Passenger Element" convey a sense of alienation and disillusionment with the world. The speaker feels like they are living in a world where everything is transient and easily replaceable, a world where genuine connection and meaning are hard to come by. The repetitive refrain of not knowing what side they're on and feeling half in love and underground speaks to a lack of direction and purpose.

Ultimately, the lyrics highlight the sense of isolation and being lost in a world that seems to lack meaning or connection.
