Some context: from March onwards Billboard changed its ranking methodology to include Youtube streaming numbers; this is how Harlem Shake took the #1 spot after it became a meme. What was an attempt to better reflect consumer taste has, in my opinion, become a ways to flood the charts with music approved by teenagers and white people. In the end the biggest songs were "edgy," "controversial" or "misogynist," its dissemination kosher because a white guy's singing it.
Locked Out of Heaven because it's at least imitating something that has worked.
No one but teenagers with undersized brains listens to "singles" type music, and whites have the numbers and the money, so singles charts are
supposed to reflect that.
