It doesn't matter if it's a CD, a Film, or manual with the instructions to build a spaceship. If you copy it, the original owner doesn't lose anything. If you don't copy it, the only one missing something (the experience) is YOU.
Enjoy!
Of course, if you happen to have some extra money for donations to creators, please do so. If you don't have that, try contributing with a review somewhere or recommending the content, spread the word. Piracy was shown to drive businesses in several occasions by independent and biased corps (trying to show the opposite).
When copyright holders can remove access to paid content on a whim, or destroy already finished works because it's somehow more profitable than selling them, or simply don't care about preserving the works they claim to be responsible for, archiving them even against their wishes is not only moral, but a moral imperative.
Culture is more important than profits. And if preserving culture is illegal, the law is wrong, and must be ignored until it's been corrected.
