Cover art for She Knows lyrics by Gnarls Barkley

yeah, he said in an interview that it's about his mother's passing and how he wishes she can see the man he has become, compared to what he was in his past, when she was alive. But this is like his message to his mother that he knows she can see him now, and that he's become a decent man and is no longer the thug/hoodlum he used to be.
