Price drops, prices rise, etc.

1. Price drop: If the price of music downloads drops, consumers will choose to download more music with the same willingness to pay. This will cause the demand curve to shift to the right, indicating that consumers who demand more music at the same price will be more inclined to buy more music.

2. Price increase: On the contrary, if the price of music downloads increases, consumers will reduce their demand for music with the same willingness to pay. This will cause the demand curve to shift to the left, meaning that consumers who demand a smaller quantity of music at the same price will be more inclined to purchase less music.
