NewJeans will struggle in Global Spotify until the next album and potentially beyond.
Global Spotify K-pop is driven by SEA - Indonesia, Thailand, Philippines, Myanmar and Vietnam. At Supernova's peak, SEA pulled in 1M streams (42% of global). The problem with NewJeans is they lost the SEA market. How Sweet only pulled in 300K-400K streams from SEA vs. 1.4M~ with Super Shy and OMG. How Sweet failed to chart at all on Spotify Indonesia daily (with a bar of 140K daily, when peak NewJeans in Indonesia was hitting 450-500K daily). We see this on Youtube Indonesia as well, with How Sweet pulling 1M on their debut week vs. 2.5M for Armageddon, 2.9M for Super Shy, 2.6M for Ditto, and 2M for OMG. While not as drastic as Indonesia, it does appear NewJeans has lost views/streams in the other big 4 SEA countries. The launch of ILLIT, BabyMonster and anti-ADOR rhetoric online in English speaking spaces have damaged NewJeans in SEA. I don't think a JP album has any hope of recovering this.
The other big market is the US, but NewJeans have also 'came back to Earth' from the peak of Super Shy in the US. When Super Shy came out, it was a follow-up to OMG which was insanely viral in the US, especially in K-pop and Asian American spaces (multiple weeks on Youtube US at 1.6M weekly, hovering top 40-50) and led the blow up of K-pop in the US with Blackpink, especially in Asian American circles like Head in the Clouds, Dabin/Porter Robinson EDM and major festival circuits like Lolla/Coachella. The hype was insane with a 4M opening week on Youtube, but fell back down to 1.6M weekly after. Despite this, Super Shy was pulling a peak of 1.1M streams on Daily US Spotify (700K after the first week), which was insane since K-pop normally doesn't pull on Daily US Spotify (Supernova didn't chart a 370K bar, Easy charted with a peak of 540K). How Sweet failed to chart the 370K bar as well, but Youtube US shows the initial hype was on par with OMG (1.6M weekly), there just wasn't enough continued play and How Sweet failed to go viral. The NewJeans US fanbase that supported Super Shy is less 'stan' than 'trendy', and the trend this year is catchy lyrical lines (Espresso, Good Luck Babe) and rap drama which How Sweet failed to deliver.
ADOR however did manage to save NewJeans reputation in South Korea, and they still dominate Melon with a #2 and #3 song, despite a weak rollout, bad press and less trendy music. While NewJeans was able to maintain their position in Korea mostly intact, they lost market share in Japan to the JP groups (Easy by Le Serrafim, Magnetic by ILLIT, Sheesh by BabyMonster), were not able to capitalize on a strong campaign last year in the US to another one this year, and have lost quite a few fans in SEA due to drama and increased competition. I expect Supernatural to compete with Easy and Magnetic but it will be tough without JP members. All eyes will be on the new album, where NewJeans should assert their dominance in South Korea and attempt another viral campaign in the US/SEA to gear up for a world tour, but without US/SEA I expect it will be challenging for NewJeans to hit their Global Spotify peaks again.
