she's okay with you listening to Metallica and Avenged? Well, NIN has some explicit content, but it's really not THAT bad. I don't see why you should be able to listen to Metallica and A7X but not NIN.
Oh, and I don't know if you know this or not, but NIN is just one guy. I believe his name is Trent Reznor. One-man band. If I recall correctly, he also did the music for War Craft I. Very talented.
