When I first bought music, it came in the form of 45's, so the tune was probably something that was playing in the Top 40's back in the day when Casey Kasem was actively doing the show. (maybe the Osmonds? ) I was in 6th grade. I can't remember the first album I actually bought, but back-in-the-day I had a whole stack of 45's, and a cool case to keep them in.
Album selection has been ecletic - Pop, Rock, C&W, folk, international folk, and classical. None of which I have in my possession as I no longer have a turntable to play them on.
Don't own an iTunes, have never downloaded music electronically.
