I'm not a huge radio guy.. I only listen while driving somewhere, so pretty much only in the car.. and the stations I listen to are all classic rock, so its A VERY odd occurrence for me to hear a tune on radio I'm not familiar with.. although it HAS happened.. but not very often.. When I DO hear a tune from the 80's I like that I'm not familiar with, its like finding the Holy Grail.. when all you listen to is one genre that is 40 years old and you find material you're not familiar it, its pretty exciting..
I think you've got something going on by sleeping with radio on over the years.. there is NO telling what all subconsciously is rolling around in your noggin.. do you sometimes get weird cravings for stuff you've never had before? Foods or drinks that used to be advertised that you never got around to trying? Weird desires to vote for Dewey? Its an interesting thing to ponder.. I'm almost envious...
Friendship is like peeing your pants.. Everybody can see it, but only you can feel the warmth..
