Query: Some "essential", but more "non-essential"

I agree with many of the reviews I've read here. Sure, there are many "great" songs here, but many of his "greatest" are missing. I feel like I was once again duped by the "Repackaging Gods" into buying yet another "Essential" compilation that contains more "Non-Essential" so-called hits. Putting "Waltz No. 1 (Nunley's Carousel)" and "Invention In C Minor" was the ultimate slap in the face. Advice: Grab all your favor CDs and burn your own compilation, and save yourself a major disappointment (not to mention $$$).
