A collection of baubles from Cher's oeuvre may not initially seem like a reason for celebration.

A collection of baubles from Cher's oeuvre may not initially seem like a reason for celebration. After all, her long and colorful career has already been documented on numerous compilations. What makes this 21-song set special—and well worth owning—is that it combines material from several labels and key periods of the artist's musical life. While there are several omissions that will spark complaints from diehards (like the 1971 classic "The Way of Love," for example), the highlights are undeniably plentiful. Perhaps most fascinating here, though, is not merely Cher's formidable string of hits but how remarkably effective she has always been at keeping in step with trends—while never shedding or compromising her own unique qualities. In the end, that's what separates the rare true icons and legends from the momentarily successful who eventually fade to black. Believe.—LF
