For a lot of jobs now, a fairly detailed audio mock-up has come to be expected. Here's the absurd metronome marking from recent pop orchestra job I worked on:
I asked the arranger (who is actually quite brilliant at this sort of work) if I could just put something standard there, but he was on such a short deadline as this whole project was a rush job, and the file still had to be worked on by the MIDI guy who was completing the mock-up, that he said just to leave it. I'm sure the studio musicians who were recording it must have thought it was ridiculous, but perhaps they are used to seeing stuff like that now.
The overnotating trend to make the computer playback as exact as possible is definitely not a good development IMO, and often results in a lot of superfluous notation that actual human musicians do not need, but unfortunately I think we are going to continue to see more and more of this as a fairly precise audio mock-up is now becoming standard and expected for new works.
