Well, catharse all you want with your squankings, but please let me get out of earshot.

How can you say this? Jazz has produced some of the most beautiful songs ever conceived. Just to name a few that you might want to check out:
Louis Armstrong: West End Blues
Bix Beiderbecke: Singin' the Blues
Rhapsody in Blue
Count Basie: Jumpin' at the Woodside
Artie Shaw: Begin the Beguine
Erroll Garner: Misty
Anything Billie Holiday or Lester Young
Miles Davis: Kind of Blue
Dave Brubeck/Paul Desmond: Blue Rhondo ala Turk, Take Five
Body and Soul

I'm sure these would change your mind about the "squankings." (Obviously, you don't want to listen to Charlie Parker.)

Jazz is America's music. It's creative, lively, beautiful and inspiring all at the same time. The amount of emotion that some of these artists had was astounding. Jazz fueled the roaring '20s and got the nation through the Depression and it's not something to brushed aside as wasteful, meaningless noise.
