thanks to all who commented, there'll be update on weekend.
Some notes about the music: (thanks to miskinsincap)
the singer was (is) a famous arabesque musician (ghetto music) at the time of cassette players. He was especially popular among bus/minibus drivers. The song was his #1 hit; probably sold millions of copies, has become a classic of the genre. The lyrics have become a general expression for any type of depression . While the song can be interpreted as a long curse to the whole existence itself, the part in the game can be roughly translated as:
'Let this world fall apart,
let this dream come to an end,
shame on the one who laughs while he makes others cry'
