Every year there are one hit wonders in every genre. Of course trap queen is number 1, no one wants to drive around on their way to a party bumping apparently. It's just the trend of the times like how power ballads died out.The #1 single in the game is "Trap Queen". The biggest song last year was "Hot nikka". Not like I'm making this up. You are talking about a handful of artists who sell albums and even then only a couple of them are reaching platinum. I'm talking about the rap game as a whole.
