This is a parody of the background video for the song "smooooch・∀・" from beatmania IIDX 16 EMPRESS. It's a song by kors k in the style of "CANDY RAVE".
You won't get a good MP3 of the song for a while, since the official soundtrack isn't due for quite some time. If you know the right places to look however, you can find bootleg MP3s of EMPRESS's songs.
If you like this song, you oughta check out the music from the rest of the series.
(BTW, Aleu, the "[H]" refers to the "Hyper" notechart difficulty, but isn't a part of the song title; I'm assuming you got the name from a gameplay video.)
No problem Aleu, I'm always glad to educate people about beatmania IIDX.
Comparing this to the original video, urushi did a good job of making a parody/remake. I wonder if he's done or plans to make a finished version? There's three girls in the original video.
