OK, this confirms it ... I really am the nerd of the group
high school was Neil Diamond, Gordon Lightfoot, John Denver, Eagles
College - I expanded my horizons and added in classical and some country (my sister was a real country/western fan and she was the closest relative to me as far as physical proximity - she'd come and pick me up and we'd spend Saturdays' together .... course the radio was turned to her station and she loved Willy Nelson and Waylon Jennings and such)
After college ... got addicted to various kinds of jazz, blues, motown, big band and other 30's-40's music.
Today, I listen to a pretty wide range of types of music and musicians .... usually it's more about the song they sing then the style of music, and about their voice and if it can catch and keep my attention, but Eagles, James Taylor, Tom Jones, Neil Diamond, Gordon Lightfoot all of those still figure pretty heavily in what I love to listen to.
