Could someone tell me what's the name of this music video?

Well, yesterday, I saw a music video of vocaloid, and I can't find it now again. In the video, there were all the vocaloid members, and at some parts (or the whole?), they were in a school. The point I remember the most is that there was a cute chibi Miku drumming crazily for some moments xD *-* The music definitely wasn't slow, it was like disco or rock music, I can't really remember, but it was rhythmic, I'm sure. Could someone tell me the name of this video (or a link?) from this silliness I've just wrote? ^^
