About the music. I used to watch Tour of Duty aka NAM - Dienst in Vietnam. I heard that when it was aired in the US for the first time, all the music was instrumental only. But I saw the later version with real songs. And I loved it way better. I think it depends on what version you saw and fell in love with first. For example SPN's 1st season is available on iTunes but without the classic rock songs. Fans are livid of course :)
