always entertaining box amply proves." Authors Mary A. Bufwack and Robert K. Oermann commented that her later RCA singles, "stand the test of time as among the most powerful country female vocal performances of the 1970s." In the early 1970s, Smith started recording more songs penned by Dallas Frazier. The pair had become close friends, which prompted Frazier to write songs for Smith that reflected situations in her personal life. Both Smith and Frazier described her 1970 single "Where Is My Castle" as being autobiographical of her recent marital troubles. "Anybody knows that its cathartic to sing how you feel about things," Smith later said. "Where Is My Castle" reached the top 20 of both the Billboard and RPM country singles charts. In 1971, RCA released Smith's cover of Don Gibson's "Just One Time". Backed by a large rhythm section, the recording reached number two on the Billboard and RPM country charts, becoming her most commercially-successful single of the 1970s. Her eighteenth studio LP of the same name reached number 14 on the Billboard country albums chart and featured liner notes written by Loretta Lynn. With Smith being among RCA's top-selling recording artists, she had enough leverage to coax executives to let her record another gospel album. The result was 1971's Come Along and Walk with Me. The studio album featured gospel tracks penned by spiritual writers such as Dottie Rambo. In 1972, Smith had three back-to-back top singles on the Billboard country chart: "Just for What I Am", "If It Ain't Love (Let's Leave It Alone)" and "Love Is the Look You're Looking For". RCA released the singles on three separate LP's: Ain't We Havin' Us a Good Time (1972), If It Ain't Love and Other Great Dallas Frazier Songs (1972) and Love Is the Look You're Looking For (1973). Her most commercially-successful album was If It Ain't Love And Other Great Dallas Frazier Songs, which reached number 14 on the Billboard country albums chart. The studio project was recorded as a tribute to Dallas Frazier and featured ten songs penned by him. Frazier also sang several duets with Smith on the project. Before leaving her contract with RCA, the label released more LP's, including the compilation, Dream Painter (1973). Its title track would chart in the Billboard top 40. 1973–1979: Record label switches, pop music incorporation and semi-retirement In 1973, RCA promised to give Smith a better royalty
