Dude Sings Lady Gaga Medley About Darth Vader, The Joker And Hans Landa

I am so confused. On one hand, this dude is singing a medley of Lady Gaga songs. Sure, her songs are catchy but at this point, they're already annoying because let's face it, Gaga is overplayed. But on the other hand, the medley is about movie villains The Joker, Darth Vader, Hans Landa and Fox from Wanted.
