2. Queen, "Bohemian Rhapsody" (1975)

"I see a little silhouetto of a man, Scaramouche, Scaramouche, will you do the Fandango? Thunderbolt and lightning, Very, very frightening me. (Galileo) Galileo. (Galileo) Galileo, Galileo Figaro Magnifico."
(BOM. BOM. BOM. BOM. BOM. BOM. BOM! ...we were all thinking it.) "Bohemian Rhapsody" is composed of several distinct vignettes, and nothing else exists quite like it, partially because it's so musically and lyrically peculiar. These words are many questions, but for the most part these questions don't need answering, because the point of this song is singing along even when you have no idea what's going on. There are decipherable parts about kicking ass, but the segment quoted above is one of the most awesomely and agelessly confusing. And yet, we all know it by heart.
