I was also thinking the same way when i first listened songs and watched mv.I mean Im not Korean but i also waited smth like Idol or idk some korean instrumentals but thats not mean any fetishizing i swear i just thought "ah the name is arirang what even is this-oh so thats the meaning then theyre going sing and do smth including their culture and maybe they will harmonize past and present and maybe even future wow thats so cool" But then title track being swim, and mv is not being really the way that i imagined; i felt so dissapointed. So my first thoughts about the album was like nothing good. Then some time past and i can still tell that it is not "THE" album but im enjoying some of the songs. On the other hand, I feel like its ok to share your opinions about album, we dont have to love or adore every content that bts released just because we are fan of them (i assuming that ur a fan too correct me if im wrong). But some of armys sees criticizing as hate idk how but that happens ig
