Jon is an amazing singer, full stop. The moments where he bursts into song are always welcome for this reason.
- The main theme to the show. It took a break for a few episodes, starting with the Bubsy critique, but came back for Banjo-Kazooie: Nuts & Bolts.
- His Sanity Slippage song right after he snaps upon seeing the Bafomdad, it's probably one of the few examples where his actual singing shows as opposed to the singing he presents in the show.
- His cover of Katy Perry's "Firework" is frigging awesome. Jon has a surprisingly good singing voice. This is in no small part due to him studying music.
- "The League and I", a wonderful parody of "You and I" by Lady Gaga.
- In his first update video after leaving Game Grumps, Jontron performs his rendition of "Nessun Dorma" and nails it. This was done as part of a Non Sequitur joke.
- The Alex S. remix of the Jontron theme, used for the epic Theme Music Power-Up from the "Takeshi" episode. Then the final version came out, being equally amazing as the mini-remix.
- Schmoyoho's epic autotune remix of the "Titenic" episode, although it takes its chorus from a StarCade episode.
