What song is Kyoko dancing to in Puella Magi / Mahou Shoujo Madoka Magica? I've just been re-watching Puella Magi Madoka Magica / Mahou Shoujo Madoka Magica (episodes, movie, doesn't change this situation). I noticed a song that sounded quite nice, that Kyoko was dancing to (playing Dance Dance Revolution, if you're happy to go by that name) in the 6th episode, or at 1:20:25 roughly, during the first movie. I'd like to make it clear that I am referring to the first song she dances to, not the second. I am well aware that the second song is Connect by ClariS.

The scene can be found at this link. It starts right near the beginning. What is this song / tune? Does anyone know the name, artist, or what it is from, if it is known outside of Madoka Magica?

Thanks in advance,
It's part of the song Connect. You can say it's a remix version. The title is Connect -Game Installation-

It's from Mahou Shoujo Madoka Magica Special CD 6 (track #13).

Mahou Shoujo Madoka Magica has total 6 Bonus CD. From what I could see, the artist is still ClariS. (I actually has all the bonus CD)
