I love some random foreign artists that I don't speak the language of and can't understand at all - Saian Supa Cru, Dengue Fever, Kent, Sigur Ros, Vicentico.
On a side note, I saw BTS on UK TV once and thought it was some kind of comedy pastiche act. What I heard and saw was really terrible, yet the panel on the show were lauding them when it was over, and I just didn't understand. K-pop is likely not for me, I figure.
K and J pop is absolutely grating to my ears, but they're billion dollar industries for a reason. They took the west's version of boy and girl bands from 30 years ago and turned it up to 11.
I'm not a fan either, though in terms of musicianship and songwriting quality most of it is far above contemporary american pop. I completely understand why kids would prefer that to the endless "three chords and autotune without a hook" slop.
k-pop fans are very toxic and some of them even harbour Anti-Japanese sentiment which is a racist & misinformed sentiment
I'm not accusing the entire k-pop fandom of being like this but their are obviously factions within the fandom who can be very vocal and very hateful fueled by anger & negativity
Edit: typo that changed the meaning of what I was saying
