Here is a cover of "Cruel Angel Thesis" done by the best of all the Hatsune Miku contributors, "ryo".
Ryo's original material for Hatsune includes "World is Mine", "Black Rock Shooter", and "Love is War" which are the three best songs in her lineup. You can also go here for a YouTube playlist of all his solo works to date. He is also a member of supercell, who as a group make Hatsune Miku songs.
Also as a bonus here is a crummy iPhone picture of my new Hatsune Miku Figma on top of my speaker at work making her appear to be at a concert blowing minds... and souls.
