While Queen's a Night at the Opera has hits like "Your My Best Friend" and "Bohemian Rhapsody " but the AMAZING song is The Prophet song and it somewhat gets overlooked because of Rhapsody, and it's a musical masterpiece in my opinion. 

Here is a YouTube video of the prophet song.

Here is a video about the making of the Prophet Song

The fun part is I have no idea what the song is about besides a prophet who has a vision. 

I dreamed I saw on a moonlit stair Spreading his hands on the multitude there A man who cried for a love gone stale And ice cold hearts of charity bare I watched as fear took the old men's gaze Hopes of the young in troubled graves I see no day, I heard him say So grey is the face of every mortal

Um Sure...
