I'd be interested to hear how better gear has changed others' taste in music.
In high school, I listened to pop (saw Billy Joel 3 times but Van Halen only once

), but also was very into classical music performance; nearly became a music major (fortunately I didn't). Peter Gabriel and Kate Bush in college. Then came the dead years when I worked too much to know anything. Then 90s gangsta rap, accompanied by the Beasties, Beck and Ben Folds Five. Then. . . folk, acoustic, alt-country.
Now that I've discovered my ears again, I'm still into my folk and alt-country, but I'm also rediscovering the classical that I left behind in high school. Even discovering a little jazz as long as there is some tonality to it. Looking up at my shelf, in addition to my old stuff, I've got Nine Inch Nails, Muddy Waters (Folk Singer), Elvis Costello's North, Patricia Barber, Linda Ronstadt, Brian Bromberg, Glenn Gould, the Mackerras Beethoven set, the Bernstein Mahler set, Steely Dan (what movie was it? "If I ever start listening to Steely Dan, slice my throat with an Al Jarreau records), and the wonderful Curzon Mozart on Esoteric that's in my ears right now. Never would have happened without the headphones.
Anybody else experience anything like this?
