Or at the very least each train could have a different song playing during the ride that's randomized (like Cosmic Rewind). "Tokyo Drift" is an obvious one, but songs like "Danza Kuduro," "We Own It," and "How We Roll" being in the mix would fuse well with the ride, especially because music is one of the things that's part of the whole franchise's identity. Remix them with sounds of tires screeching, characters calling out, whatever, and I think it'd really bring the whole experience together in a way that makes people/fans go, "Yeah, this is the F&F I know."
