Have you noticed that Disney pretty much hates cats? In that regard, it's quite fitting that the first villain song in the company history comes form the mouths of Si and Am, two identical trouble-causing Siamese cats.
I used to watch Sword in the Stone all the time when I was a kid. It wasn't among my favourite films, but it had lots of positive energy, which this scene showcases magnificently, even though it's not a much of a song.
"The World's Greatest Criminal Mind" by Vincent Price
This underappreciated Disney gem has Vincnet Price as its bad guy ... and he sings. It's Disney's first proper villain song and still their best, because you can't top Vincent Price. Rumour has it animators sketched Price's exaggerated gestures while he was recording his lines. Music is by great Henry Mancini, by the way.
"Gaston" and "Gaston (reprise) & "The Mob Song" by Richard White and others
Celebration of the village's most celebrated man is turned into his desire to marry beautiful Belle in the song's reprise. And then there's "The Mob Song", which is more straight-forward in Gaston's motives.
How do we now that Jafar is a bad dude? He steals Aladdin's song and turns it against him. It's not a long song but it wonderfully turns Aladdin's greatest moment from an earlier part to his defeat (almost).
Oh dear, here we go. Because everything has been said about the animation, and especially how it takes cues from The Triumph of Will, let's focus on the song itself. Jeremy Irons, who voices Scar, starts the song but his part is seamlessly taken over by the great Jim Cummings, who can actually sing. Mr. Cummings is one of those actors whose name one doesn't recognize but has actually been in many childhood favourite films.
After their hooray into scifi-influenced movies in the beginning of 00s, Disney finally returned to from at the end of the deacde. The Princess and the Frog also marks the return of a proper villain song, and it was worth the wait. Other songs in this movie were somewhat flat, so this colourful sequence easily stands out.
Great movie; poor, flat, forgettable songs. This song doesn't actually reveal the villain's motives but is designed to fulfill them, as Gothel manipulates Rapunzel. There's also a reprise with an even more sinister feel to it. Unfortunately I couldn't find a good version of it, so sorry about the poor quality in the last video of the list.
For Disney, for their wonderful animated films and their amazing villains with their catchy songs in which they love to tell their villainous schemes and motives.
(No, this doesn't include the straight-to-DVD sequels beacuse ... do I need any arguments?)
