Yes, he did. This is a rip from Guitar Hero: Metallica, a console game that uses the band's original instrument stems to improve the game's experience. That being said, a comment buried away on a Justice song's RU-vid section threw in the idea that Lars wasted an enormous amount of tape in the making of "...And Justice For All". Quite how much is left up to interpretation, and I'm not sure how much of this person's insight is based in truth (ironic given the album's focus on truth), but there you go.
