A drug is neither moral nor immoral -- it's a chemical compound. The compound itself is not a menace to society until a human being treats it as if consumption bestowed a temporary license to act like an asshole.
The manner in which Americans consume music has a lot to do with leaving it on their coffee tables, or using it as wallpaper for their lifestyles, like the score of a movie --it's consumed that way without any regard for how and why it's made.
Do we really want to know how Michael Jackson makes his music? No. We want to understand why he needs the bones of the Elephant Man -- and, until he tells us, it doesn't make too much difference whether or not he really is bad.
