The thing I liked about that album was that by rapping from another perspective, he eliminated one of the biggest flaws of himself as a rapper. Cole's music is so singular and focused on his perspective, what he thinks, etc. Me, me me. When you do that while also being "conscious" it becomes easy to come off judgmental or just annoying. The few concept songs he did where he rapped from other perspectives felt very one note. Lights Please is like the classic track that started it all for him...but that shyt always felt paper thin and one note to me. Almost like a soulless attempt at making a Nas song.
4YEO has flaws, but the concept and that last track really give it more feeling than his other albums for me. He finally creates a fully developed concept/person who feels like a real person. I thought he did this well on his next album (KoD) well, especially that track about his mother. He's improving. Some rappers just do that shyt effortlessly out the gate like Common/Nas/Kendrick/etc, because they're introspective and evocative lyricists. Cole strikes me more as a punchline rapper who gained consciousness and started evolving on the mic.
