Almost every episode has had at least one musical performance except for "Rollercoaster", "Lights, Candace, Action!", "The Lizard Whisperer", and "Mommy Can You Hear Me?". Some episodes have two or three in a row. Phineas and Ferb The Movie: Across the 2nd Dimension has the most songs with 13 songs. "Rollercoaster: The Musical!" is second with 9 songs.
