30 Greatest Hits zeroes in on Aretha Franklin's prime recording period for Atlantic, from her breakout in 1967 with "I Never Loved a Man (The Way I Love You)" through the end of 1974, during which the Queen of Soul truly reigned over the charts -- she averaged over one pop hit every two months. This two-disc set delivers all of her classics ("Respect," "Do Right Woman, Do Right Man," "(You Make Me Feel Like) A Natural Woman," "Chain of Fools," "Think," "Spanish Harlem," "Rock Steady"), plus much more excellent material for those who won't recognize much more than the songs (and there are quite a few) that have entered the cultural consciousness ("I Say a Little Prayer," "The Weight," "Spirit in the Dark," "Day Dreaming"). It's a great foundation to any collection that has yet to be equaled by a pair of Rhino sets, the two-volume Very Best of Aretha Franklin from 1994 and Aretha's Best from 2001.
