"Mad World" is a 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 #3 on the UK Singles Chart in November 1982. Both "Mad World" and its B-side, "Ideas As Opiates", would turn up on the band's debut LP The Hurting the following year. 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 reached #1 in the UK in December 2003, and became an international hit. [from wikipedia]

LYRICS
All around me are familiar faces
Worn out places
Worn out faces
Bright and early for the daily races
Going no where
Going no where
Their tears are filling up their glasses
No expression
No expression
Hide my head I wanna drown my sorrow
No tomorrow
No tomorrow
And I find I kind of funny
I find it kind of sad
The dreams in which I’m dying are the best I’ve ever had
I find it hard to tell you
I find it hard to take
When people run in circles its a very very
Mad world
Mad world
Children waiting for the day they feel good
Happy birthday
Happy birthday
And I feel the way that every child should
Sit and listen
Sit and listen
Went to school and I was very nervous
No one knew me
No one new me
Hello teacher tell me what’s my lesson
Look right through me
Look right through me
And I find I kind of funny
I find it kind of sad
The dreams in which I’m dying are the best I’ve ever had
I find it hard to tell you
I find it hard to take
When people run in circles its a very very
Mad world
Mad world
Enlarging your world
Mad world
