yup, I am a guy in his sixties, and I bought that beastie boys album when it came out- when, my guess would be, "you were still sucking on you mamma's tit, man", to quote the Beastie Boys.
Remember, hip hop and rap started at the same time as punk rock- in about 76. So you have to be pretty old to have been listening to rap, or punk or even metal, since it started.
not to say I dont also appreciate a bit of rock nacional, especially of the 70s, which was the era for us sixty year olds...
