"A throwback to the most blissful moments of Nineties R&B that has a 21st-century appeal, 'OMG' is a pristine pop song with a glowing — and glowed-up — heart at its core," Rolling Stone said on June 16. The title song of NewJeans' first single album has earlier ranked 74th on Billboard's Hot 100, a weekly song chart that ranks top 100 popular songs. As of June 16, the music video for OMG gained more than 24 million views on YouTube.
