A well deserved bump.
These are pretty darn old and well known I think, but maybe someone haven't seen them yet:
Miku Hatsune - Melody
Miku - Anger
Miku - Love is war (this > Len version, says I)
Gotta love techno Miku and rock Miku.
Oh, I found a 3rd part to the Daughter/Servant of evil story, and it actually made me cry a bit. ; - ; Embarassing.
