Those "through the history" compilations seem to really rake in the views, I've noticed. Another good example is the "Tell Your World" PV
I know right, the Miku Generations video literally brought me to tears because of it. It is not even that long ago, but it just makes it all wonderful because over the years from the first concept to what it has become now... wow!
As for Tell Your World, I actually dunno which one I like best, Google's edition or the MMD video of it, both are just as nice. I guess when you mix the real people images in, it just makes her that much in contact with you, spiritually and through the sound of her voice.
Recently however, I re-discovered an artist called 96Neko, needless to say I been listening to all the songs she resang from vocaloid songs. She has a great voice! Gotta admit she does a better Senbonzakura than anyone else, and certainly any vocaloid... it is the only one that isn't squeaky pitched. (mind you I like Miku's voice but this song seems pitchy for such an awesome track.)
