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

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