Understand that the demand curve shows the relationship between the price of a good and the quantity demanded, holding other factors constant.
Recall that a change in the price of the good itself causes a movement along the demand curve, not a shift of the demand curve.
Identify factors that cause the demand curve to shift, such as changes in consumer income, tastes and preferences, or prices of substitute goods.
Recognize that a change in the price of substitute goods affects the demand for the original good, causing the demand curve to shift.
Conclude that only a change in the price of the MP3 players causes movement along the demand curve, not a shift, so it would NOT shift the demand curve.
