this much should be obvious to anyone who was listening in the Comeback Season/So Far Gone era.
The sound he had that got him noticed doesn't even share similarities to what he sounds like now, which is pretty damning an indictment of his pen. Early Kendrick still sounds like Kendrick. Like the same 'character', just further along in the seasons of the show.
Drake's pen sounds like it's been Aunt Viv recast 4-5 times at LEAST.
I, ironically, believe that he has the most hand in his R&B/Pop singing outing than his bars by far, and I even think dude has a good staff that works with him on those sounds - good enough to carry a career in that lane alone. Hell, the number of tracks he has writing credits on for non-rappers is high and pretty quality.
I don't think Drake could freestyle. I don't think he could sequence a record and be able to move bars around and rearrange them in post to adjust the track. I don't think he could have gotten 20 minutes of bars and then moved and spliced things during the process of the beef the way Kendrick threw in rebuttal bars after the fact and then dropped so people were thinking he fully recored MTG/NLU after Family Matters when he very much did not.
I think Drake is a pop artist. And if he'd accepted that and leaned into that, no one would be on his neck about it like they are. No one cares that The-Dream wrote Umbrella for Rihanna. But if they found out he also wrote Jay's verse; there would be conversations.
Drake just wants to have his cake and eat it when that just isn't his bag.
He's definitely been fraudulent from multiple directions though. But there is a talent in being that adaptable/malleable as to move from fad to fad like he has. But being that moldable means you don't have a shape of your own. And... that's pretty much the Story of Adid Drake
