Do you mean Decoded? I just looked through it again, to check. He doesn't mention Beyonce at all during the section about "Lost Ones". He actually goes out of his way to not mention who the song is about. He says, "I don't want people to listen to 'Lost One' after reading the decoding and say, 'Oh that verse is about so-and-so'; what I really want is for them to listen to the song and say, 'Oh, that verse is about me.'" This is all in the epilogue at the back of the book. Maybe there's another part of the book (or another book?) that you read that I missed? No shots or anything, I just never thought it was really cleared up who the verse was about.
I always thought the "Lost Ones" verse was about Rosario Dawson, who Jay dated before Beyoncé.
I went to one once, when I was working for an accounting firm, and I wanted to shoot myself.
This is my exact worse nightmare.
And you have them synchronized and playing on repeat 24/7!
This is completely insane.
The "just deserts" revelation just shattered my entire universe.
