It would appear that Konami has given a shout-out to the dance game for the Dreamcast that was inspired by Konami's own Dance Dance Revolution games: Feet of Fury.
In Harmonix's and Konami's Karaoke Revolution Party, if you get a platinum record (20000 or more) on the sing and dance mode (microphone + dancemat combo) on expert , you get a trophy that says "Feet of Fury".
The font that is used in the logo is an exact duplicate of the Feet of Fury logo.
You can see a screen capture I took with a digital camera, and read comments by Dan Potter of Cryptic Allusion (the makers of Feet of Fury) in this thread on the Cryptic Allusion forums.
