"Thinking of You: The Atco/Cotillion/Atlantic Recordings (1973-1985) isn't just unwieldy in its title; for timing reasons, four of its eight albums have been split across discs to accommodate bonus singles. While this isn't the ideal presentation for a "complete albums"-style box, the set is nonetheless comprehensive and wholly enjoyable thanks to Sister Sledge's upbeat blend of R&B, pop, and disco ... Thinking of You is filled with the joyous sound of sisters making music together. It's beautiful, indeed".
