Ha! Villain songs are so funny! My favourite villain song of all time is In the Dark of the Night, which is in Anastasia. But, sadly, that's not a Disney film. So! My favourite Disney movie villain song is probably Be Prepared, from The Lion King (seeing a theme yet?). Yeah...probably that one.
Honorable mentions: Poor Unfortunate Souls | The Little Mermaid // Cruella De Ville | 101 Dalamations // Gaston | Beauty and the Beast
