He has won a Grammy but Nas admits that sometimes he doesn't check the exact facts of his rhymes. Talking about his 2002 song "I Can," Nas says sometimes he makes mistakes. "You can sit back and say, 'Let me perfect this' and 'Let me perfect that,'" Nas said in an interview, "but I was never that kind of artist. I've made albums where I slurred words, I've done crazy sh*t. People feel that. When [Rev] Run says 'It's three of us but we're not the Beatles,' he thought the Beatles had three people. It didn't matter. 'I'm the king of rock,' not the Beatles, is what matters. As far as the line in 'I Can,' Alexander the Great and all those guys all affected each other. You can't read about Napoleon without hearing about Alexander The Great, and vice versa. You might read one book about it, but that's that author's account of what happened. Someone else might say a whole different story, but if I speak on what happened in one man's book, then that's what it is."
