Are there any Vocaloid songs that remind te of Severus Snape?

I want to add some new Vocaloid songs to my iPod, so I'm wondering which ones remind te of Severus Snape. Please add links to the songs (on YouTube o NND), the titolo of the songs, and which Vocaloid the song is by. I will listen to all songs te answer the domanda with, and some I might even already have on iPod! :)
