Do the words “Dance Dance Revolution” ring a bell? Particularly the 4th and 5th mixes (which are import-only because Konami of America is too STUPID to get on the ball and…ahem) if you can find them.
A sampling:
Orion.78 – A lively, happy, fast-pased Enka-style song…about a potluck dinner. I swear I’m not making this up. Once you understand what the lyrics actually mean, this song makes The Banana Boat Song sound like a friggin’ aria.
Wonderland (UK Extreme Mix) – The original was, like countless other disco songs, an exhortation to get on the floor and dance. This remix is mostly about the singer very loudly insisting that everyone kiss him. Over and over and over. Insert your Ecstasy joke here.
End of the Century – I’ve read and reread the lyrics, and as far as I can tell, the entire song consists of freaking out over the Y2K bug. Yeah…that bad.
So Many Men – The singer explores polyamory. Noteworthy mainly because, while a lot of us practice it to some extent, we’d never dream of discussing it, let alone putting it into a song that’s going to be heard by millions.
Moonlight Shadow – A wonderfully melodic Celtic-style song…about a bizarre murder. With six gunshots. I got chills when I saw the complete lyrics for the first time. Why do so many lovely songs turn out like this? :sad:
Let Them Move – Uh…there’s this DJ that’s totally unprepared and really, really violent. And after all the equipment breaks down or sumpthin’, she tells everyone on the dance floor to just dance without music. Right. 
Love This Feeling – This sounds like someone who’s on Ecstasy (move like Goldfinger???). And since lovin’ what you’re feeling is what usually happens during an Ecstacy trip, well…
Dam Dariam – “I need your love. Which, of course, is why I run away screaming every time you try to give it to me.” Sheesh, it any wonder that she uses nonsense phrases?
Walkie Talkie – Just one man expressing his undying devotion to a two-way radio. (And you thought Aaron Neville’s tribute to cotton was weird.)
Oh…just so you know I’m not making any of this up, go to Dance Dance Revolution Extra Mix FAQs, Walkthroughs, and Guides for PlayStation - GameFAQs and click on “Music and Lyrics FAQ” for the complete list.
Away from the arcade game front, Capitol Steps has some pretty funny parodies. My favorites are The Bomb Saddam Song and Bomb Bomb Iraq.
