Uncompressed source audio for iconic video game soundtracks is fun to find and to listen to, but it's not the "real" music.
I get what they are saying, but at the same time you really don't have to listen to the restored content. They are hardly replacing the original soundtrack. It is merely a nice to as a what if scenario. Then again, i am not some purist who needs everything exactly how it is. Some of these Donkey Kong Country 2 restored music is fantastic.
