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.
