At 150 BPM it should sprint, but the energy sits at 4 and the groove is almost sideways: high danceability, low pulse, a rhythm that leans rather than drives. In 3A the tonal centre keeps slipping between bright and bruised, so the happy and sad tags aren't contradictions — they're the same chord read two ways.
There's aggression in the edges and relaxation in the middle, which is why it works after hours rather than peak time. It builds a room with soft walls and a hard floor: you can move to it, but you can also stand still and let the texture do the work. In a set, it's the odd left turn that makes the next straight line feel earned.
