The Dark Side of the Rainbow

The Dark Side of the Rainbow refers to the practice of watching the 1939 film The Wizard of Oz, and listening to Pink Floyd's 1973 album The Dark Side of the Moon at the same time. Most suggest starting the album on the third roar of the MGM lion.

The music syncs to the movie's plot surprisingly well; getting dramatic in dramatic movie scenes, or matching thematically, like playing "Brain Damage" during a dance of the scarecrow character.

Pink Floyd band member have repeatedly said that the phenomenon is a coincidence.
