I don’t get the idea that blackpink are original or their lyrics have more meaning. Their lyrics(most of their releases) looks like the typical idol songs where love/crushing on someone is the Main theme. Like their performance is very “different” out there right now compared to the current trends(not necessarily new)but their lyrics are kinda standard kpop lyrics and what their fans drag other groups for singing about. Also the oppa in boombayah totally fits or am I the only one who reads lyrics, they are singing about their crush and wants to be with him aka their oppa. I’m not bashing blackpink I actually quite like them and they make some great songs.(wish YG would release them from the dungeon)
