Soundcheck is a boy band that Ms. O and Otto, along with almost everyone else loves. The only known person who ever didn't like the band is Olive, though, she later changed her mind and is now on-and-off about them.
A parody of boy bands, Soundcheck consists of Tony D., Danny T., Johnny J., and Ringo.
Some of their songs are:
- "Take Away 4"
- "Up, Down, Left, Right"
- "The Force of Gravity"
- "Never Give Up"
- "Shake It Like a Blender"
- "The Work of Heart"
- "The Saddest Song in the World of All Time"
- "Save the Day"
- "Christmas Smells Like Christmas"
- "Beautiful Balance"
- "Regular Soundcheck Song"
- "Odd Squad: The Movie"" (Season 2)
- Ringo's name could be a reference to the drummer of the Beatles, Ringo Starr.
- Soundcheck is mentioned in the episode "Dance Like Nobody Is Watching". Their song, "Up, Down, Left, Right" can be heard in one of the scenes of the episode.
- Danny T has apparently quit and rejoined Soundcheck multiple times.
- Danny T doesn't tell the other band members that they have a concert until right before they perform onstage.
- Tony D loves animals, with dogs being his favorite.
- Ringo loves to eat at restaurants.
- Johnny J loves sports, and has won several trophies for various sports.
- Otto has made a Soundcheck room in headquarters. It is filled with various paraphernalia relating to Soundcheck, and the background music is the slow jazz version of Take Away 4.
- In the Odd Squad Movie, the band makes a reference to Queen's famous "Bohemian Rhapsody" music video towards the end, before Ms. O was zapped with the halfinator. This is because they sing with their heads in a diamond formation, and with the same sort of harmonies that Queen was known for.
