If it's crap ... We'll tell you
I not sure if this has been done, but here it is regardless.
I think that more often than not a villain expressing themselves in song is the single greatest moment in most movies, whether their Disney or Non-Disney. They are either hilariously self-unaware, campy, or downright fucking creepy, and it's a nice breakaway from the mostly boring protagonist.
So let's try to gather them all in one place.
My personal favorite:
Love then both. Rotten Tomatoes described the first one as "A priest singing about how much he wanted to bone a gypsy," in their list of "Kids movies not for kids."
I'm not seeing a lot of connections between The Dentist song and Gaston's number.
Yes. Hellfire is hands down the best one.
Hellfire = Best villain song ever and makes other villain songs look bad
Those crossed my mind as well, but I think Samuel meant songs that are performed by the villains themselves.
I like to imagine the villains are performing these songs...
Godammit, beat me to it!
But if we're gonna do pussy show tunes (which most of these villian's songs are), this is the first one that came to my mind:
Followed closely with this if it counts:
There ain't nothing pussy about these! Fucking awesome, especially Rasputin. Lenin couldn't sing alto to save the Proletariat.
Yeah, and same with the Imperial March, although I didn't think of that either. Anything that sounds creepy works. Beethoven's Glorious 9th is a villain song.
