The mockumentary format of the show contains no laugh track, and most of the music is diegetic, with songs either sung or played by the characters or heard on radios, computers, or other devices; however, songs have been played during montages or the closing credits, such as "Tiny Dancer" by Elton John ("The Dundies") and "Islands in the Stream" by Kenny Rogers and Dolly Parton ("E-mail Surveillance"). Featured music tends to be well known, and often songs reflect the character, such as Michael's attempt to seem hip by using "Mambo No. 5" and later "My Humps" as his cell phone ringtone. Daniels has said that it does not count as film score as long as it already appeared in the episode.
