cause why would I listen to kpop if I have everything I wanted in western music already while I don't have to look up the translation to know what they mean and well the meaning is bs anw (and overall their vocal also suck). For kpop I want smth fun, sth unique that I can't have in western music or at least hard to find.
Notice what you wrote there? WHY I- exactly, not everyone are like you. That's so simple. If everyone are like you then Ive and Nj will never even become a huge force at all now. Lots of people not even a fans of kpop to begin with, so what they want is not kpop sounds but easy listening and enjoyable songs. These both groups in the top right now is exactly the prove of this. And language is a weird barrier to say about music especially when not everyone speak in English. A lot portion of people will still find a translation for themselves even for an English songs. Please see outside of your bubble.
Their songs too especially Nj doing really well everywhere and Nj even doing much better than Lsf in Japan without any Japanese members already says a lot. Why people still listen to kpop then? Because of preferences, concept, styling, visual and contents. You also don't get this from the western artists. And also if the songs is a hit, it will always a hit in every languages.
And for vocal? Yeah that's even weirder for you to say this. As you said, their vocal sucks and lots of kpop groups including lsf sing outside of their range with random high note here and there. So, you technically love groups that sounds not good because they sang outside of their range? That's on you then.
