Firstly, no copyright infringement is intended. It is simply a remix of notable elements from the iconic Tetris video game for the Nintendo Gameboy. So, I will credit the original composers such as Hirokazu Tanaka, Johann Sebastian Bach and the Russians for the Korobeiniki.
The remix itself is a mashup of the in game music itself, the Game Over fanfare and the High Score menu.
Anyway, enjoy :D
