My grandmother was my primary care-giver during my first six years, and she listened to the "adult contemporary" station back in the late 70's/early 80's so I still have a deep love of that late 70's soft rock sound, like John Denver, Linda Ronstadt, Poco, America, etc. It comforts and soothes me like nothing else, I tell you. My attachment to it is passionate and irrational.
Some of my other relatives listened to old country music, blue grass, the whole "Classic rock" sound (Pink Floyd, Led Zepplin, Rush) which surely influenced me, though I completely HATE HATE HATE "new" country music.
I remember listening to early 80's pop on the radio, and I still have a fondness for New Wave in particular.
When I started listening to my own music, I almost immediately began gravitating toward "college music" even when I was ten or eleven. There was some heavy metal hair bands thrown in there, too.
