For TJ Combo's dynamic theme, Mick Gordon, the composer, purposely made it the longest theme in the game so far, with all the variations. The reason was to give a challenge to YouTuber RKosmik, who makes videos by compiling all of a single stage's theme variations into one single track. TJ's theme clocks at around 20 minutes, where the other character/stage themes are around 8 to 10 minutes long. Surprisingly enough, RKosmik accepted the challenge and compiled the theme.
