Those were MY high school years...
I certainly agree that those were the years when social upheaval displaced the post-WWII dreams of suburban utopia... but the music was GREAT! (Disco put an end to that in the '70s)
Anyway, music is not an issue. There was some wonderful music written in the 30's, and those ween't good times, either.
I actually think that very few people honestly enjoyed the late 60's-early 70's. It's only the media that is nostalgic, because those were the years of their premier influence (Viet Nam and Watergate). They think if they keep talking about it they will regain their influence.
