At the beginning, this song sounds like a typical Usher song: he talks about meeting a girl in a club & making love (& the listener is led to assume that Usher means later on in the evening). Then Young Jeezy comes in with a rap that, beyond any shadow of a doubt, sets the listener straight with respect to the immediacy of Usher’s intentions. Jeezy conveys his point through the use of analogy, such as his reference to a grocery store situation. Finally, Usher comes back on, reiterating the immediacy of the situation, leaving not a single doubt in the listener’s mind with respect to the urgency of his desires.
