BTS's main reason of success: Versatilty....
The concept of BAP were also depicted by some other groups. Are they on same level?
And the song "I need you" that claimed the heart of SK, has it's concept anything to do with BAP or any other previous group?
Some are saying BTS got luckier!!!! Seriously?
Songs like masterpieces: Blood, Sweat & Tears, Fire, Spring Day, DNA, Mic Drop, Idol, Fake Love, Black Swan are not made by Luck.
But by immense passion for hard.
Licking over same stereotypic concept is the main reason why None before BTS could ever reach the level that they got.
Listeners don't want to listen what have been going for years after years but want what is creative. Can't blame the listeners for not sranning flowless objects.
Hype is what that go to black hole in course of some years. Creativity & Diversity is what that hold you to the throne forever.
