Parental interests.
A friend and I spoke about this today, with hilarious results.
My friend's dad had awesome taste in music as a kid (from what he told us) but when he hit that age and became a dad, it all went to hell.
Does anyone actually know of older parents who have actually kept their great tastes in anything? As opposed to liking Michael Bolton?
My mother likes some of the stuff I listen to, as does my father. Then they both like some shit.
