Deja Vu is a eurobeat song closely linked to Initial D, the Japanese anime and manga series built around street racing and drifting culture. Its fast tempo and dramatic vocal hook made it a natural fit for racing scenes, and fans later lifted short clips for car videos, gaming edits and internet memes. Because the track instantly signals speed and nostalgia for many viewers, it remains a shorthand for a dramatic, repeated moment long after its first anime association.
