That's a very interesting point you brought up. I do know that Message in a Bottle, in Guitar Hero 2, was another song that would fade out but in the game itself, it has a definitive ending. I personally would agree with you because I remember being a bit confused hearing a fade out in a Guitar Hero game, but I know there are a lot of people that prefer familiarity in a song. They'd prefer the master track to a cover because most people don't like the covers. I myself would agree with you but it really isn't a huge deal to me either way
