Three versions of "Mad World", starting with the above cover from Puddles Pity Party & Haley Reinhart x PostmodernJukebox, while below is the infamous Gary Jules x Michael Andrews' cover version - in a video directed by Michel Gondry - while at the bottom of this post is Tears For Fears' version from 1983.
""Mad World" is a 1982 song by the British band Tears for Fears. Written by Roland Orzabal and sung by bassist Curt Smith, it was the band's third single release and first chart hit, reaching number 3 on the UK Singles Chart in November 1982. Both "Mad World" and its B-side, "Ideas as Opiates", appeared on the band's debut LP The Hurting (1983).
"Mad World" has since been covered by various artists, most notably by Michael Andrews and Gary Jules for the soundtrack of the film Donnie Darko in 2001. This version was a UK number one hit and won Orzabal his second Ivor Novello Award in 2003." (Wiki)
