If you go over to your jukebox in-game and try to play Atmosphere- Findmuck.ogg you'd find that it is very different from this one on youtube Is this an error in the coding or did they replace the soundtrack in game? Regardless I'd really want to know what the name of this in-game soundtrack is as it is really beautiful and I've been playing it on the jukebox nonstop
