I never meant to imply that certain decades had good music and others did not. Of course, there is always good music to be found if you know where to look. But I hold to the assertion that money is the death of art. Not because money corrupts artists, but because people with money become the gatekeepers of artists, and people with money make terrible, awful, no-good, very-bad choices.
In the '60s, what was good and what was mainstream became the same thing. The gatekeepers with money were knocked aside by the passionate relationship between musician and audience. And it took those gatekeepers awhile to reassert their control.
Also, Neutral Milk Hotel is amazeballs. I'm kinda sad I wasn't able to see them on their reunion tour.
