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

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