However I'm curious as to who, what & where floats your boat (and which universe you occupy)?
I think
when is a more important aspect than who, what & where, because those three seem to be different at different times.
I fact, I am wholeheartedly supportive of that thing Birdjaguar said:
As I see it, there needs to be some semblance of a story involved.
So, depending on the listener's mood and condition and prior experience and many other characteristics (some of which likely are too subtle to trace and pinpoint), the listener either hears the story the music tries to tell, or not. Whether or not the story is worth hearing is a separate issue though.
To satisfy you curiosity specifically, when I was occupying the X3 universe my boat was floated by that:
But I can't say it's exactly my genre. It's just that this particular thing made my skin crawl under those particular circumstances, and it might have failed to cast that effect on me at a different moment.
BTW, movies help creating the right moment a lot. The story the music there tells is connected to the movie story or some particular moment/event/mood there, so it is a lot easier to grasp. Speaking of those, my favorite 3 are:
Also, I guess I can perpetually (or short of that) listen to reels.
In all those things repetition is massive. So I think repetition as such is not a question really. What's being repeated is. And whether it fits the specific listener (or the listener fits it).
