When the video was first posted on Halloween as a free single, it was titled "HAPPY HALLOWEEN FROM NEGAREN", featuring the cover artwork for BreezeSphere Mk.6. The video also contained a WIP of Move On before switching to AAAAAA.
When you name yourself "AAAAAA" in Undertale, instead of the regular confirmation prompt text, the text "Not very creative...?" will come up. The track's title is a reference to this.
