A theatrical cue is the trigger for an action to be carried out at a specific time. It is generally associated with theatre and the film industry. Cues can be necessary for a lighting change or effect, a sound effect, or some sort of stage or set movement/change.[3] In the audio commentary for Heat, Michael Mann says that that music from the musician Moby provides two cues in the movie. I believe that in each of the two scenes cued by Moby, timelessness is being depicted; there is also depiction of timelessness in Thief. Please see the screencaps (with captions) below for a description of this.
The first scene from Heat cued by Moby, uses music from the song
New Dawn Fades. When the music starts, Vincent appears to be
driving unrealistically fast. It's as if the camera has been greatly
sped up. In the screencap at left, we see Vincent's view of the
freeway as he's driving.
The second scene in Heat that is cued by Moby is the final scene
in the movie, with Vincent holding the dying Neil's hand. The name
of the song playing is God Moving Over the Face of the Waters. As
described below in the quote from Saint Augustine, God does not
exist in time (that is, not in time as humans experience it).

As described in part 7 of my analysis of Thief, there is an apparent
'contraction' in time while Frank and his men are breaking into the
Bank of California vault. This contraction is indicated by the fact
that it takes the men much less time to work their way into the vault,
than was earlier predicted by Frank. What's going on is that the men
are effectively in Hell, a realm in which time would probably not be
experienced in its ordinary sense.
From the Confessions of St. Augustine, Book 11, Chapter 13 (with Augustine speaking to God): In the eminence of thy ever-present eternity, thou precedest all times past, and extendest beyond all future times, for they are still to come--and when they have come, they will be past. But "Thou art always the Selfsame and thy years shall have no end."[Cf. Psalms 102:27] Thy years neither go nor come; but ours both go and come in order that all separate moments may come to pass. All thy years stand together as one, since they are abiding. Nor do thy years past exclude the years to come because thy years do not pass away. All these years of ours shall be with thee, when all of them shall have ceased to be. Thy years are but a day, and thy day is not recurrent, but always today. Thy “today” yields not to tomorrow and does not follow yesterday. Thy “today” is eternity. Therefore, thou didst generate the Coeternal, to whom thou didst say, "This day I have begotten thee."[Psalms 2:7] Thou madest all time and before all times thou art, and there was never a time when there was no time.
