Say what you want about Ms Duff...but the problem with music isn't her or her ilk.
The problem with music today is the lack of diversity, which is largely created by the way corporations like Clear Channel have hijacked the media outlets.
Morning Becomes Eclectic (on KCRW)is about the only place to regularly hear good, diverse music.
Some of us have the inclination, time, money, etc to actively seek out good music. Most people naively rely on radio/TV to expose them to the arts. And when all you get is American Idol, Blink-182, etc....well....eventually you get dumbed down.
