I don't think people realize how smart and deep CTRL by SZA actually is.
The album first starts with a woman saying something like "I was afraid that if I did not have CONTROL things would be... Fatal". And this seems like just an interlude or intro, right? No big deal. But keep that in mind.
After that the album goes on to explore all of SZA's life, her heartbreaks, the men she dated, her dreams, but also her insecurities and fears. And all throughout the album you can hear little snippets of an old woman giving what sounds like advice. Keep in mind all these "interludes" sound like a phonecall.
Then we get to the last song which is 20 Something. That song basically explores what is one of the biggest themes on the album: the fear of growing old and wasting your youth.
Then that song ends with the same woman from the beginning saying something as "And if it's an illusion I don't wanna wake up, I'm gonna hold on to it, because that would mean that the end of this would be like a hole or darkness, who wants that?" and that's when you realize the woman is talking about life and death and it keeps going. "So that's when I think about CONTROL" (once again the name of the album). You hear SZA say "That was beautiful momma" and that's when you realize the women talking throughout the album were her mom and her grandma. They give her advice through the phone and that plays along the album as she sings about her life, dreams and insecurities. And the album starts and ends with her mom talking about not letting the fear of growing old get to you, not fearing life and not fearing death. And that is control - CTRL.
