ClascyJitto is the name that JC releases all VGM under (with albiet, very few exceptions).
The most significant is the music Clascy made for the game "Pizza Tower"
Fun fact: As well as being a reference to the animation studio "Klasky Csupo", the name ClascyJitto is a rearranging of the initials JC.
(JC -> CJ -> ClascyJitto)
