Not a troll thread. All music ages and some ages worse than others.
As an expert on the subject of both groups I would have to say honestly that BlackPink music will be the most dated of the two.
Hell I think it's already happening today in 2021. BlackPink may have started the trend but other groups like Everglow and Idle and StayC have just taken it to a whole other level. Meanwhile Blackpink has just stayed stagnant with their sound. Theres been no growth and expansion of their style.
BTS on the other hand will be okay in the sound department. Their music won't stand the test of time like The Beatles or The Rolling Stones but it should still be tolerable in a decade or two.
Then again I may be completely wrong. And both groups music will still be loved decades from now. Pinocchio and Hot Summer both turned 10 this year and to me they still go harder than anything out today.
What do you think? Who's music will be cherished the most in a decade or two?
