Having listened to the Kanye album quite a bit over the past few days, I have been having mixed feelings over "Freestyle 4." On one hand, I think it's one of the sonically stronger tracks on the album, but on the other, I can't help but wonder if it's something that never got round to being finished.
I love the effects on the vocal, and the way that Ye flows on the first half of the track over the "Whoo" sample as well. I think the "Freestyle" in the track really begins at the 00:45 mark.
Having seen Kanye perform live a couple of times in my life, I've experienced firsthand his tendency to go off on a tangent at any given time mid-show, and I feel like that's where his head is at for a moment in the track. It really does feel like a proper freestyle, it feels like he's come right off the dome on this one, and then we get introduced to Desiigner's hook.
I reckon this hook was initially laid down to the beat for Kanye to build the full track round, but perhaps after going on a mad one, decided to hit record and really was feeling the freestyle he dropped. And in true Kanye fashion, he thought, "fuck it," I like this and it's staying put, the track doesn't need anything else. It serves as a great interlude but really leaves me wishing there was more. For me this is the essence of what I love about Kanye. His attitude is marked all over this track.
