Alicia Keys, "Un-thinkable (I'm Ready)"
In 2003, a gutsy Alicia Keys asked her love interest for a date on "You Don't Know My Name." On "Un-thinkable (I'm Ready)"-the standout song from her latest album, "The Element of Freedom"-the singer/pianist goes from entertaining puppy love to confessing deeper emotions. "You give me a feeling that I've never felt before . . . it's becoming something that's impossible to ignore," Keys sings nervously over extended piano strokes. She finally builds up the courage to share a serious desire with her lover ("I was wondering maybe, could I make you my baby?/If we do the unthinkable, would it make us look crazy?") atop a building, thumping beat. For an artist who has built her career on songs about love, lust and heartache, Keys has never sounded quite as vulnerable and exposed as she does here. -Mariel Concepcion
