It’s been shown repeatedly that a large part of piracy isn’t about cost, it’s about convenience. It was easier to pay $0.99 and get what you wanted when you wanted it, than download 8 files off of Napster and hope that one of them was actually a decent bitrate and was the song the title said it was.
“We think there is a fundamental misconception about piracy. Piracy is almost always a service problem and not a pricing problem. If a pirate offers a product anywhere in the world, 24 x 7, purchasable from the convenience of your personal computer, and the legal provider says the product is region-locked, will come to your country 3 months after the US release, and can only be purchased at a brick and mortar store, then the pirate’s service is more valuable.”
