The internet. From Youtube, to Pandora, to Spotify, to access to great stuff like KEXP it's made music infinitely more accessible. With music I think it's less about a change in tastes as it is the exposure to them and the ability to select what and when you want to hear it. Beats the **** out of listening to Rock 108 in high school and having them play Metallica, Rush, Offspring, and Pink Floyd EVERY ******* day between 9 am and 10 am (art class!!!!). Those days were brutal.
