Dance Dance Revolution, the song's Oni steps, what are they?

[frag]

I apologize beforehand if this has been addressed in another topic, but it's hard to search for something like "Dance Dance Revolution" in this forum

Anyway, it was pointed out to me today at the arcade that the Oni steps on the game's title song were basically allusions to the more famous songs. I saw B4U, Afronova, Dynamite Rave, et cetera but I'd like to know if anyone has a more helpful or complete list. Also, I noticed that the background synth (the orchestra-hit sounding synth) sometimes mirrors Twilight Zone, but I don't pay much attention after that to see if there are any other auditory references.

Any help would be appreciated as it makes this song a lot more enjoyable!
