Istanbul (Not Constantinople) - Slowed Down 800%, The Bierberization of by CaptainCaustic
Their 1990 classic remake "Istanbul (Not Constantinople)" has been "Bieberized": slowed down 800%. A formerly just over 3 minute song now takes 20 to play. Listen; it sounds like it would be an appropriate soundtrack to 2001: A SPACE ODYSSEY.
