It's all here! Lionel's saccharin croon the delicately plucked harp and a singer who doesn't "know what love is" but knows what he's "feeling." "If you know what's really in your heart," Richie sings, "you won't let them tear us apart." The coup de grace comes as the song's fading out and Richie delivers the titular line over and over again. As his daughter's sometime friend, sometime rival might quip, "That's hot."
