The document summarizes three conceptual music videos:
1) a-ha's "Take On Me" uses stop motion animation and live action to tell a story of a man entering a comic book world.
2) Panic! At The Disco's "Emperor's New Clothes" continues from a previous video, showing a character transforming awkwardly in a surreal graveyard after falling from hell.
3) Katy Perry's "E.T." shifts from depicting a desolate end of the world to a futuristic scene with changing music, continuing its futuristic theme to match the futuristic style of the song.
