Yea, I'm not going to listen to music I want to listen to for the first time on a crowded noisy tube thanks.
(Like the first time one has sex, which has rom-coms and romantic fiction instill on us that it has to be "special"?)
I've discovered and first heard all kinds of great music on the tube and other casual places, and didn't hurt my later re-listening and appreciation of them...
Though this is only for maybe 3 projects a year so it isn't how I listen to all new music.
I like to do that too, but if you're anything like me, most of your early music, you listened in high school or college in whatever kind of crappy quality (e.g. downloaded mp3 or crappy cassette copy depending on age), random conditions, etc, but still connected fine with it.
