Sketchbook name ideas

I've just reached my sixth sketchbook, which means that A, I've unlocked the achievement for finishing 5 sketchbooks, and B, I need to find a name for my new child. I give my sketchbooks names, it helps induvidualize them and stops me from getting them mixed up, and is meant to match the contents. I've been drawing a lot of music related stuff lately, like DJs or band members, as well as stuff from Rain World & Silksong. My previous sketchbook names are: Project, Bassdrop, Chromatic, Spiral & Hyperchromatic. I want another sound related term like Dissonance, Supersonic, or Shockwave. I also have a few ideas for more magic or spacey words like Astra.

I like to name sketchbooks based on what I want to put in it, what I think will be in it, what I want to draw right now, my current hyperfixations (Starset, Silksong, Rain World) and my overall mood lately.

Does anyone have suggestions?
