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

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