Pruett continued recording for MCA Records. The label released a series of singles by Pruett during the mid 1970s that failed to become major hits. Songs such as "My Baby's Gone", "I've Taken" and "She's Still All Over You" reached positions outside the top 40 of the "Billboard" country singles chart. In 1977, the single "I'm Living a Lie" reached number 30 on the country chart, becoming her highest-climbing single of the past several years. The same year, Pruett left MCA and signed with Mercury Records as part of the label's Nashville artist expansion. According to a "Billboard" article, Mercury developed a marketing plan to help promote its newer artists. The label also intended to release four LP's by their artists as part of the plan. However, the intended plans did not occur for Pruett. The label's only single release by Pruett was "I'm a Woman" (1978), which only climbed to number 94 on the country chart.
