In 2021, K-pop was all over the place musically, much like every other element of the world in the second year of the Covid-19 pandemic. Reliable acts put out music that didn’t necessarily match their typical standards of excellent musicality or put out less music than usual, and many shifted their focus to English-language music. Meanwhile, newer acts strode onto the stage with surprisingly addictive releases that became among the most memorable of the year.
Despite, or because of, the changing of the K-pop guard, 2021’s K-pop soundtrack was undeniably eclectic and full of anticipation for what’s to come in the years to come.
Here are the 20 must-know singles of the year that one writer thinks we’ll all be listening to for years to come.
