Korobeiniki
"Korobeiniki" (, Peddlers) is a nineteenth-century Russian folk song that tells of a meeting between a peddler and a girl, describing their haggling over goods in a veiled metaphor for courtship.
Outside Russia, "Korobeiniki" is widely known as the " Tetris theme song", from its appearance in Nintendo's 1989 version of the game. It is also known as the "Tetris Type-A", since it appeared in the game mode.
