"Mad World" is a song by the British band Tears for Fears. Written by Roland Orzabal and sung by bassist Curt Smith. The song would eventually become Tears for Fears' first international hit, reaching the Top 40 in several countries between 1982 and 1983.
Nearly two decades later, the song made a popular resurgence when it was covered in a much slower, ballad-like style by composers Michael Andrews and Gary Jules for the soundtrack to the movie Donnie Darko. This version became an international hit.
