HOWTO: Get a "free" iTunes lockware song with every Pepsi

Apple's got a new iTunes-Pepsi promotion wherein a certain number of Pepsi bottles will have an under-cap coupon good for a "free" (that is to say, heavily restricted and 0wned by paranoid record companies) iTunes Music Store track. If that's the kind of thing that interests you, you can guarantee that you will get your "free" track every time by repeating the trick that was invented for the last one of these promotions: tilt the bottle until you see what's printed on the underside of the cap.
