I doubt Kanye would ever sabotage Nas. He’s a Nas stan and has said multiple times that Nas is his favorite rapper.
It was simply lack of planning and narcissism. If you listen to Kanye speaking about the album, he truly acts like he gave Nas a classic. Like he BELIEVES that shyt whole heartedly.
I actually like Nasir for what it is, I listen to it regularly, but there’s no doubt that it SHOULD have been better. Kanye was on that bullshyt and the only album that didn’t suffer from it during that era was the one that he actually spent TIME crafting, which was Daytona.
Hell I think if you gave Kanye and Nas a MONTH in the studio together, you’d get a stone cold classic. Instead Kanye wanted to play MAGA Superman and fumbled.
