In a perfect world, a UN-resolution would exist that demands every fan of 20th century pop music to listen to the four-disc juggernaut Back to Mono once a week, at the very least. For those poor souls who can't handle that much Phil Spector, this 19-track collection does the trick nicely. You get the wall-of-sound's most classic hits: "Be My Baby," "Then He Kissed Me," "Baby, I Love You," "He's a Rebel," "A Fine, Fine Boy" and so on. Quite simply, these songs never get old -- never. Each and every one is a mini-symphony dripping in romance and heartache.
