It's not the kind of song that I'll ever add to my playlist but I totally get why it's so popular.
It has popular artists from different regions so it's reaching a larger audience. It's got the nostalgia factor in the sound, it's fun and catchy. I've already seen it being used in reels of non-kpop circles.
It has even reached the anime community. It is charting high in Japan which is the market that BP or Rosé has not able to touch.
