OMG (NewJeans song)

"OMG" is a song by the South Korean idol girl group NewJeans from their single album of the same name (2023). ADOR, a division of Hybe Corporation, released "OMG" for download and streaming on January 2, 2023. Park Jin-su produced the track and composed it with Ylva Dimberg and David Dawood. The lyrics, written by Dimberg, Gigi, and NewJeans member Hanni, were inspired by high school dramas and explore themes of young love, dedication, and one-sided affection. It blends R&B, hip hop, and pop, featuring hip-hop percussion, trap rhythms, and a UK garage-inflected groove. The song includes plucked staccato synth chords, skittering cowbells, and layered vocal harmonies and percussion.

Buoyed by its viral success on the video-sharing platform TikTok, "OMG" peaked at number 10 on the Billboard Global 200, number seven on the Billboard Japan Hot 100, and number two on the South Korean Circle Digital Chart. It peaked at number one in Singapore and on Billboard's Hits of the World charts for South Korea, Taiwan, and Vietnam. The song received positive reviews for its lyrics and catchy production. NME and Billboard ranked it among the best K-pop songs of 2023.

Referencing Park Chan-wook's 2006 film I'm a Cyborg, But That's OK, the music video depicts the members with different mental illusions. This connects to "Ditto" through shared uniforms and themes. To promote "OMG", NewJeans performed it on South Korean music programs, international music festivals, and awards shows. The Recording Industry Association of Japan and the Korea Music Content Association certified the song platinum for exceeding 100 million streams. It won Best Song at the 33rd Seoul Music Awards, Song of the Year at Japan Gold Disc Awards, and received a nomination for Top Global K-pop Song at the 2023 Billboard Music Awards.
