Featuring art-pop singer Grimes, “nihilist blues” is Oli’s personal favorite song on the album. The song talks principally about nihilism, focusing on the meaninglessness of life, existential crises and pessimism. Some of its lyrics have been teased in a video posted by BMTH, called “amo [rec] vol. 1.” Oli also talked about the collaboration with Grimes:

We saw an interview where she said she liked our band a few years ago. But my wife’s obsessed with her and she was like, “She’s not going to do it, she doesn’t do collaborations,” so when it came through it was like, “Christ.” Grimes said she listened to 30 seconds of it and was like, “Yes, get me on this.” It might sound cheesy, but just her acceptance of the track when she gets people asking her to collab all the time… We were buzzing.

Musically, “nihilist blues” sets inspiration from old disco and EDM songs, as Jordan Fish commented:

We’ve got a soft spot for that stuff—tacky ‘90s euro-sounding club stuff! The chorus melody in that song sounds to me like old school UK dance music—like the notes are not quite right. Oli and I like that vibe, so we just took it where it wanted to go. On the last album, we’d not have dared to do that. This time we didn’t feel afraid to take it absolutely where it wanted to go.

There are some easter eggs on the music video:
