Yes, it is, however, besides legality, is there anything wrong with that? I like to think of "morality" when it comes to issues like this in terms of "effect on owner." If it's not released, and someone just rips it from the game, then it's not doing anything to the owner as there was no opportunity to make money off of them. If anything, it's good and free publicity, and gives people a stronger connection to the game (and thus, its sequels.)
That was way too many commas.
Problem is I never brought the morality of any kind of copyright infringement into the discussion. If we're talking legal, then both "real" piracy and ripping resources from a given work counts as copyright infringement, and thus are both a crime. Justifying yourself with "Yea, it's not legal, but I'm not hurting anyone as much as people downloading the whole thing" is kinda hypocritical. I could just as easily justify myself "I'm not hurting anyone by downloading Fallout New Vegas because I never would have bought the game in the first place and my copy didn't stop anyone from enjoying their legally purchased copy, thus no money gained or lost."
This isn't about you. I'm bringing morality into this because this is a multi-faced issue. I already agreed that it's copyright infringement. You can't argue that. It's law. If that's "okay" or not is thus what should be discussed. I don't see how it's hypocritical. Especially when your example includes full games when we're talking about a game's soundtrack. Keep it consistent. Are we talking about parts of the game (an argument closer to sampling in music than downloading albums) or the games as a whole? The subject at hand is a specific portion of a game that isn't available to be purchased (when other games do have this available to be purchased.) Should people just not download the soundtrack when it isn't available to purchase? Simply because it's illegal? I really don't think so. If anything, disregarding legality, that the studio would be happy to have people enjoy their work and I already mentioned the institutional benefits of this. This is why musicians are typically in support of piracy. They lose the CD sale, and get the concert and t-shirt sale. Developers and publishers will get the sequel sale. The brand loyalty sale. Etc.
"This isn't about you?" What?
I simply said that both are copyright infringement and thus both illegal. If we're looking it legally, then no, you SHOULDN'T be ripping soundtracks, because it is the law. Now, if we look at it practically, yes, it does serve to promote games. A friend of mine bought Nier because of listening to an illegally obtained OST, thus giving the developers money. And piracy can work the same way. I could pirate a game, see that I actually like it and then pay money for a legal copy. Did I break the law in both cases? Yes. Did the developers gain a sale? Yes they did. The hypocrisy of some people is that the former seems to be perfectly ok, while the latter is frowned upon and put in the same basket with people who pirated the Charity Bundle.
