I can't remember who it was - maybe Brian Eno - but some important musician guy said he recorded ambient noise from a city street and after he listened to these field recordings for the millionth time, it was like, "Oh yeah, at 1:23, that's where the car horn comes in." So when you're doing stuff like this, and you've been working on it for a year, you're like, "Oh yeah man, that makes perfect sense!" And then you forget when you give it to people, they're bewildered.
