Not sure about 'pop music', but all the music I listen to is recorded in the 1960s and later.
On the other hand, most of the stuff made after 1970 is nails on a chalkboard to me (really, most stuff made after 1960, excepting things like the "Ballad of the Green Berets").
Then again, pretty much listen to classical (or John Williams, which, despite mostly being movie sound tracks, is basically classical).
