Lotte World Adventure is a large indoor and outdoor theme park in Seoul, South Korea, where recorded announcements guide visitors between rides, shows and facilities. A short starting cue like this one is a practical part of that system, marking the boundary between background park noise and a message people need to hear. Online, the clip circulates mainly as a recognisable park sound rather than a song, shared by visitors and editors who want an instant, place-specific cue for travel videos, park memories and announcement-style jokes.
