Hit Jazz

A type of music or theme song for a character that on paper sounds like it shouldn't fit the character at all, but in execution, wraps back around to working entirely. Mostly by being a really, REALLY good song.

Person1: "Man I love the DBZ Fighterz soundtrack, especially Hit's theme!"

Person2: "The emotionless assassin character with a jazz theme? How does that make sense?"

Person1: "Exactly! It doesn't! But somehow it loops back around to making perfect sense! Who doesn't love a little Hit Jazz?"
