Released posthumously in 1968, 'Dock of the Bay' by Otis Redding stands as a poignant anthem of the 1960s, blending soul with a touch of folk rock. This era-defining track captured the reflective spirit of a decade marked by social change. Its laid-back rhythm and contemplative lyrics resonated widely, leading it to top the Billboard Hot 100—the first posthumous No. 1 single in U.S. chart history.
