In his essay “The History of Psalm Singing in the Christian Church" as found in Sing a New Song: Recovering Psalm Singing for the Twenty-First Century, Terry Johnson notes how Psalm singing was eclipsed (at least in part) by the amendment of the Psalms themselves:
“Ironically Watts’ hymns and Psalm paraphrases were the primary vehicle through which hymns finally were accepted into the public worship of Protestants, yet not without considerable controversy in the eighteenth and early nineteenth centuries. Still it was not until the middle of the nineteenth century that hymns began to overtake the Psalms in popular use."
