Future is awesome, but he's also largely derivative of the music Lil Wayne was making five years ago. That Auto-Tune wail that's become the Atlanta rapper's signature? Wayne invented that. Listen to "Prostitute Flange," listen to "Me and My Drank," listen to The Drought Is Over 4, and listen to all of the weird leaks that popped up right before Tha Carter III dropped. He used bad vocals to convey emotion, as opposed to the digital crispness of T-Pain, and now the style's been lifted by everyone from Lil Durk to Meek Mill. Wayne deserves some kudos for its ubiquity.
He fathered what's arguably the most popular style in rap right now.
