Drake doesn’t sound like he’s having fun anymore. In a different world, Aubrey Drake Graham might come off as Keyser Söze on “The Heart Part 6,” the most recent volley (at least for now) in the extremely busy, extremely fun Drake/Kendrick Lamar feud. “The Heart Part 6” is the song where Drake says that he planted a fake story about having a secret 11-year-old daughter and says that Kendrick’s “Meet The Grahams” cover art was a setup, a way to reel Kendrick in. But Drake doesn’t sound like the master manipulator that he claims to be. Instead, he’s beat-up, surly, tired. “The Heart Part 6” is a Band-Aid, a chance for any remaining Drake partisans to claim that he’s really the winner of this past week’s events. We know better.
