Me too, in fact I've always been a very private person when it comes to what I'm doing on my computer so I never do anything sound-related on it without headphones, this does lead to my parents and sister having to scream at the top of their lungs if they want me and I'm listening to music or something, but I don't consider that to be to much of a drawback. On that note, I don't skip the intro because no one hears it but me.
