Whatever sort of music Clarence has — parodied versions of existing songs, the theme music, the episode scores — they're bound to be catchy.
- The opening theme, "King of the World
", really gives a shine to the premise and the character's adventures. It even has a variant for "Goldfish Follies", where the entire opening sequence is in sepia tone and the theme song is given '30s vibes, which gives nostalgia to that era. - The end credits theme, "Good Habits (and Bad)" by Saba Lou, is a soothing melody sung by a child, whose lyrics talk about common things from childhood and how she is always feeling fine. It is accompanied by images of the night sky at Clarence's neighborhood, creating a very nostalgic and heartwarming atmosphere in the show's end credits.
- "Hit the Piñata", a song that plays during Jeff's piñata training montage in "Pilot Expansion", has a nice rhythmic tone while describing the basics of the eponymous task.
- "Weird Things" in the episode "Lil Buddy" is a parodic take of Randy Newman's "Strange Things" from Toy Story. But rather than being about a toy being neglected by his owner in favor of his rival, this song has a Clarence's life go another direction when he missed one recess all because of his Li'l Buddy doll, then becoming gloomy. Both gutwrenching and enjoyable at the same time.
- "Ameri-Ham Dreams" from "Hoofin' It" plays off as funny and randomly awesome.
- Lizard in the Sunshine" is a take on "Blister in the Sun" by Violent Femmes, played in "Lizard Day Afternoon" as Clarence and Sumo chase a lizard around Aberdale. Enjoyable.
- "Towering Intellect" from "Slumber Party" has Radiohead's musical vibes while describing Jeff's personality. It could almost be Jeff's leitmotif.
