Those trashy tropical house rehashes and Rihanna rejects are still better than anything on ARTPOP or Joanne. 
And so what if 2NE1 disbanded? Their music was still great. Unlike ARTPOP and Joanne.
As for your statements on Paramore and Evanescence, they're your opinions and all, but "Misery Business" isn't their best song, and Evanescence still had songs on their other albums that were good. Not amazing, like anything on Fallen, but yeah. Their status as a nostalgia act shouldn't be discounted on ATRL, where Britney stans run rampant and you, a Little Monster who stans for Lady Nostalgia herself, are having this conversation with me.
