Ambient?

Lately I've been listening a lot to CBC's satellite radio Galaxie Ambient. I like it and here's what I've learned so far:

1. Ambient music is creepy and soothing.

2. Hours can pass before I notice that it's actually not been the same song playing the entire time.

3. I don't understand why anyone would want to dance to sounds like these or model human-computer interaction on experiences like these.

Topical suggestions, explanations, clarifications, protections, negations, lamentations, afflictions, seductions, prolongations and projections are most welcome.
