Rock out, PSI King.
- "Cosmic I (Smell The Universe)
as performed by Jack Black, a melodic, Psychedelic Rock number sung by a Brain in a Jar.Now I can feel out the galaxy
And hear the flow of time
Been so tense, but now I sense
A reason to this rhyme
Oh, I can smell the universe
And I can taste the sky
And I can see each molecule
Through my cosmic eye - "Musical Tour" features an expansion on the themes from the first game, giving even more of a Danny Elfman-esque motif, as well as a medley of other themes featured in the game.
- "Hollis' Hot Streak" is a jazzy tune that combines the percussion and horns of Psychonauts with Cuphead, and a dash of Grim Fandango tossed in.
- "The Questionable Area?" is the theme of the titular second hub, and a delightful bluegrass-type number that underscores the calm atmosphere of the least-uptight hub and serves as a nice callback to the Whispering Rocks music of the first game.
- "Meat Circus" makes its return from the first game, except this time with Raz's entire family joining in.
- "Compton's Cook-Off" has "Ram It Down", a catchy, jazzy tribute to old-school game show theme songs. Then there's "Ram It Down Harder" the heavy-metal cover which plays during the boss battle against the Gluttonous Goats, an absolute headbanger of a rock song perfect for a high-paced battle.
- "Forgetful Forest" is a rework of the nighttime theme of Whispering Rock, except even creepier.
- "Nona's Quilt of Memories" is a warm piece that plays while Raz traverses her mind, which is represented by, well, a quilted world.
- "Children of Grulovia" is an irritatingly catchy tune in the vein of "It's a Small World After All", full of hilariously inaccurate propaganda.
- The final battle against Maligula escalates the main themes of the game, with some of the Lungfishopolis themes tossed in (which makes sense since both Maligula and Raz are depicted as two Kaijus battling, the latter having been effectively turned into Goggalor again).
