By far - the best Steely Dan album of them all.Great songwriting combined with a who's-who list of some of the finest musicains of their era equals a classic that will be played and played by every generation that has an ear for musicianship at it's highest level.Witty, humorous, cutting, biting, sarcastic, jazzy, funky, rocking.Aja is all of that and more.This album finds "a groove" beginning with the opening track and never wavers.An often overlooked classic that should be in every collection.
