Yes obviously. I am just trolling. All saying that if they are really lossless means is if the person that made it encoded it in a lossless format. Meaning the copy of the copy you are getting by all means should be the same quality as the original with no loss of data whatsoever. So basically the question is if the lossless that is currently availble just a lossless copy of an mp3 or lossy file.
I know what it is that you and I want though. A fully CD ripped audio file from the official OST release of which it is then directly and correctly ripped into a lossless format.
That also would depend on the mastering of the CD too. If it sucks, then there's nothing any of us can do, except get into audio mastering and return back here using a time machine, punch the audio engineer that does the mastering and you made it right yourself and release it to the Internet.
