@SpenceEdit: That paints a lot into the picture for me, thanks.
@Hal 9000: Thanks for confirming that a lot of editing is just being convincing in what are probably ridiculous sound hacks ^_^

So it sounds like a lot of the effort is spent using hacks to get music out of your way, presumably so that you can omit it alltogether or add it back in, synchronized with whatever scene you’ve inserted. Is this correct?

An obvious follow up question is, what do you do where you cannot get the music out of the way/replace it? Does the music then dictate what you can or can’t convincingly do, edit-wise?
