I really like his way of talking about their music. It resonates with me. I don't fully have access to the profound meaning of their lyrics as someone who has to rely on translations but I still feel the magic and connection between all of it.
It's the consistency with some surprise, the etherealness, the beauty of the lyrics and how the story flows together.
I might as well add that kpop idols rarely get nominated in any category.
I only remember BTS and (g)i-dle, were there others, maybe older?
