Yea I never really thought about it, I just really liked the song. I never thought he was singing in a different way or anything, but I guess I just didn't notice. Either I'm just not used to payign that much attention, or I really am tone deaf.
As far as the age of the listener, I suppose it goes both ways. She was playing me a bunch of classic rock and asking me if I liked it, and most of it I said no. Sure I don't mind someone playing some Ozzy or something while I'm around, but I'd never listen to it on my own. I checked iTunes and realized the oldest music I have is 1983, and that's Metallica.
