"R.W.B.Y. vs F.N.K.I." is the score accompanying the Vytal Festival match between Team RWBY, represented by Weiss Schnee and Yang Xiao Long, and Team FNKI, represented by Flynt Coal and Neon Katt, in the episode "Never Miss a Beat". It is included on the RWBY: Volume 3 Soundtrack.
The song is notable for its jazzy big band horn sections and re-interpretations of previous songs on the RWBY soundtrack.
The track opens with the sound of Flynt's Trumpet, which leads into the first two verses and chorus of the song "Neon". The song then abruptly transitions to a jazzy horn and upright bass rendition of "This Will Be the Day", with Casey Lee Williams scat-singing the vocal line. This is followed by an instrumental jazz section including the aria from "Mirror Mirror" before closing with an upbeat horn, electric guitar and bass rendition of "I Burn".
We're all born with a dream
We wanna make come true
The best will climb to the top like me
The rest will end up like you
I bet it's hard to live with
Knowing that you'll never be this fine
Don't be distraught don't be sad
You gave it your best try
Listen, girlfriend....can't you see?
I'm all of the things that you'll never be
I'm cool like the rain and I'm hot like the sun
I'm a neon rainbow and you're no fun
- Jeff stated at the RWBY Music panel at RTX 2016 that Casey had trouble with scat-singing, constantly sticking to one sound. To help her, Jeff showed her an old Sesame Street episode.
