I felt all of Joe's points were valid and agreed with mostly everything he said.
With that said, I fully understand Drake's frustration with a failed rapper basically critiquing the moves of the most successful rapper in history. It's kinda absurd in theory. It would be like David Carr talking about Patrick Mahomes having a bad game.
He took personal and petty low blows, but I think it hurts him more coming from Joe because Joe is from the same field as him and he also was a Joe fan at one point. He literally sounded like a Budden knockoff in the early stages of his career.
