Could be. I dunno any other Sega rhythm games that debuted in arcades first before PC/consoles.
Crackin' DJ ?

maiamai, Chunithm, and Ongeki also debuted in arcade but they're modern arcade games so probably Crackin' DJ's more fitting.
So would that make her somewhat of an "air head"?
Lol, may be they'll make that kind of joke if the game's made by SEGA of America / Europe.
If I had to guess these videos depict the birth and death or suicides of the anodes created by Sega. As in these are experimental phase with the prototypes dying.
Oh, so that's what those "failure" means... The prototypes that went unused...
