Finally!
I think Yasutaka Nakata-composed stuff is very geared towards Hatsune Miku adaptations. That Perfume one... Electro World, it's one of my most favourite Miku performances. There was another one of his unreleased songs... Reizoukou ni nattou I think - super addictive.
Lividus is personally my most favourite original song composed for her even though she may not necessarily fit that type of song. It reminds me of Zabadak (a bit). That's a good thing.
I am so expecting a Hatsune Miku anime some time in the future... and fan-made eroge... and with the second Vocaloid coming out soon we'll have a whole big family of Vocaloids (with only one Japanese guy - Crypton, please please please make a male for the Vocaloid2 series someday...)
