The easy answer: depends on the file and it's proscribed method of listening.
The specific answer: I believe ISOhorny is meant to be listened to while awake with it in the background, like you would a subliminal file, especially considering its length.
On isochronic files in general: some of these files are meant to be used as one would use a subliminal file, listening in the background, while others are meant to be listened to while in trance.
Files built to be listened to one way are generally going to suck when listened to in another manner. Listen as proscribed by the author.
I think we need an advanced topics primer to direct people to for questions like these, there's not much in the way of new-person resources aside from older material.
