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.

Theft loss.
From your source verbatim, emphasis mine:
A theft is the taking and removal of money or property with the intent to deprive the owner of it. The taking must be illegal under the law of the state where it occurred and must have been done with criminal intent.
Piracy of digital media would not meet that threshold set by the IRS. If any media publisher is deducting this type of “loss” from their taxes it sure reads like they’re committing tax fraud.
