From the Onion's interview with "Jazz" filmmaker Ken Burns:

Whenever I speak to the jazzerati, the jazz Nazis who want [the documentary] to be an encyclopedia--and of course it can't be--I just ask them quite simply, who among the current players is as important as [Louis] Armstrong, [Duke] Ellington, Charlie Parker, Miles Davis, or John Coltrane? And there's dead silence. ... most Americans feel, and have told me on the road, that they feel they need an advanced degree or some esoteric knowledge to understand jazz. And of course they don't at all. Armstrong himself said, "There ain't but two kinds of music in this world, good music and bad music, and good music is what you tap your foot to."
