"Ditto" is a song by the South Korean girl group NewJeans, released on December 19, 2022, by ADOR, a label of Hybe Corporation. The producer 250 composed "Ditto" with Ylva Dimberg, who wrote the lyrics with the Black Skirts, Oohyo, and NewJeans' member Minji. With a sound rooted in Baltimore club, the track incorporates a balladic electronic and dance production with influences of house, breakbeat, and UK garage. The lyrics are about reminiscing a platonic love. "Ditto" topped South Korea's Circle Digital Chart for a record-breaking 13 weeks. It peaked at number eight on the Billboard Global 200; topped the charts in Indonesia, Singapore, Taiwan, and Vietnam; and reached the top 10 in Japan, Hong Kong, Malaysia, and the Philippines. Music critics praised the wintry, minimalist, and nostalgia-inducing production and deemed it a refreshing alternative to the maximalist sound that had saturated the K-pop market. The song ranked 19th on Rolling Stone's 2023 list of the 100 Greatest Songs in the History of Korean Pop Music, being the most recent entry. The accompany music video was shot in Daegu, South Korea, and depicts the group members as high-school students recording their daily lives using a camcorder. In 2023, it won Song of the Year at the annual Asia Artist Awards, Korean Music Awards, MAMA Awards, and Melon Music Awards. Later that year, both the Korea Music Content Association and the Recording Industry Association of Japan certified "Ditto" platinum for surpassing 100 million streams in respective countries.
