Where can I download Melt by Hatsune Miku on my iPod?

This song is beautiful, and I am completely in love with it.
I'm a sucker for Vocaloids X3
Anyway, if you can find website where I can download it to iTunes, or straight to my iPod, I will give a prop!.. Or two. It depends how good the version of the song is.
The Gezelle MIX is what I want, but any will do, really.
