I feel that out of all the great rappers with nothing left to prove, it's Em that still enjoys the shit out of it the most. Sure, the outcome has been shitty for my standards, but I do get that from Em, like, he spends a lot of time in the studio and I'm sure he's rapping his ass off just for the fun of it.
A lot of rappers tend to fall off, and I think it has to do with not practicing i.e. working at it enough. If you take basketball for example, if you don't touch a ball in a month you'll pretty much suck. It's not like you can lose it but it does take more constant work than rapping. What I think happens with many of them, is they get in a comfort zone and don't feel the need to practice, so they remain at that same level.
If you look at Nas, who's been saying that he's in a great zone, I think it's because that core love for rapping has gotten back into him and it fucking shows. He sounds better than on anything he did since Stillmatic.
And it's surprising how you work for something so hard, meaning becoming a great and respected artist, and then you just let it sit there. It's like saving for a Ferrari for 5 years, and then buy it but drive it only for a week.
In the Art Of Rap documentary (which I'm about to rewatch), it was Em who showed the most genuine appreciation and love for the art (along with Kanye). You could feel the passion when he was rapping Treach's lines. And on that note, what unifies Kanye and Em is the passion. They're the most (constantly) passionate rappers that I know of, at least the ones doing it on that stage and level, where you can easily get caught up in all the fame and money. Look at Hopsin, he's been showing disappointment and lack of motivation, and he's barely been through the "forces" of the music industry and massive attention.
And that is why I think Em and Kanye fans should be more appreciative of the two artists, instead of being in dispute all the time.
