"Compulsion" finishes Afterthoughts by circling back to its starting point—140 BPM, high energy, aggressive and dark, now in F# minor over 6:31. Heavy low-end, percussion, synths, and electronic drums lock into a groove that gradually tightens its grip, embodying the psychological loop the album traces. The track builds tension incrementally but never breaks, leaving the listener where they started: still moving, still caught in the cycle.
