Hellfire from the Hunchback of Notre Dame.

No contest.

One of my favs is 'Killer'. It is the theme of Yoshikage Kira from 'Jojo's Bizarre Adventure'

Unless you mean a song the villain sings, because then it would be 'Friends On The Other Side' from 'Princess and the Frog'

Every song in Centricide

Replying to GOMUL13. Oh that's good. That's a really good one.

I'd have to say Hellfire too.

Either Hellfire or Friends on the other side.

Friends on the other side.

OH, thats a good one

Hellfire (like most people say) and Mean Green Mother From Outer Space (all the songs in Little Shop Of Horrors are great).
