When I was younger my parents led me to believe that there was only two radio stations, KYXY - soft rock and KBEST 95 - the oldies station. These were the only ones that they listened to, therefore I was never exposed to anything else.
I am extremely well versed in music like The Carpenters (love them), The Eagles (amazing), The Beach Boys (to die for), Billy Joel (the greatest) and many other incredible old school acts. I thought this was the same education my school friends were getting.
Junior high was a shock when I got exposed to what my generation was actually listening to. I was astounded, to say the least. I was so curious how they all knew this new music and where all these new radio stations came from. I wouldn't say that I was sheltered as a child, but I'm actually glad that's my musical background because music like that just isn't made anymore.
