 Reaction to the episode's melodies were also positive. Wolfen Moondaughter wrote in her Sequential Tart article, "Five Reasons: Phineas and Ferb," that both "My Nemesis" and "When We Didn't Get Along" were among her personal favorite musical pieces from the series, despite the former resembling the styles of Elvis Costello, whom Moondaughter noted she carried a distaste for. A Wired magazine review of the series'soundtrack observed that despite being drastically different from tracks that proceed and precede it, "When We Didn't Get Along" "fit perfectly" due to "the genius of the malleable songwriting style of Phineas and Ferb's musical brain trust."
