Spector was the champion of commercial overproduction and a vicious enemy of subtlety, intimacy and immediacy. Therefore one of the worst producers ever, who's done much more damage to music than good. His "wall of sound" was just a way of making music listenable on shitty speakers (such as jukeboxes and early home stereos), so that the masses would buy records. He was a pro craftsman, not an artist, whose trade was to turn music into a glossy consumer product.
"When I got to California, Phil Spector had a real reputation for doing his 'walls with sound.' I just looked at it like, 'Walls with sound?' It's just padding the payroll." - Meet the frankly legendary Rock and Roll Hall of Fame inductee, Malcolm John "Mac" Rebennack, Jr, better known to the music world as Dr. John: http://www.songfacts.com/blog/interviews/dr_john/
Bastard1 is talking out of his arse. If his theory is correct, then I wouldn't have Be My Baby, A Fine Fine Boy, Da Doo Ron Ron, You've Lost That Lovin' Feeling, To Know Him Is To Love Him, Spanish Harlem, Let It Be & He's a Rebel stuck in my head so consistently.
