As the title of this message thread states, I was wondering which DDR songs are of Japanese origin. I know that not all of them are like that. For example, some versions of DDR have the song Cartoon Heroes, and I know that's of American origin.
The main reason I ask is that I've been looking for some new songs I might sing in the karaoke rooms at anime conventions, and they usually encourage people to sing songs that are of Japanese origin in such places.
