Ronstadt reflected on her evolution as a musician, acknowledging that whilst she achieved competence across multiple genres, the world's greatest vocalists operated at an altogether different level of artistry. Over her career, she deliberately expanded beyond pop standards into more sophisticated musical territory, drawing inspiration from classical singers and exploring operatic works. This progression reflected her belief that the finest artists transcended genre boundaries and conventional expectations.

Among singers she most admired was Italian tenor Luciano Pavarotti, whom she regarded as unrivalled in his mastery. Ronstadt emphasised that his seemingly effortless performances concealed years of rigorous practice and technical development. She particularly highlighted his exceptional gift for extracting emotional resonance from every phrase, citing his performance of "Nessun Dorma" as an exemplary demonstration of how technical brilliance combined with profound artistic interpretation created something transcendent.
