열대야

열대야 ("Tropical Night") is a Joseon Hiphop single whose official video went up on 12 August 2026, a week before the song reached streaming services on 19 August. The lyric is a breakup song set on a sleepless summer night: the narrator leaves an air-conditioned room, finds themselves walking the routes they once shared with an ex, and concludes that what keeps them awake is not the heat but the person they cannot stop thinking about. The video's description credits the lyrics to the channel's creator and the composition to Suno on its Premier plan, and lists Nanobanana, Midjourney, GPT Image, Veo, Kling and Seedance as the tools behind the video. The single runs 3 minutes on Spotify.
