A song that everybody need but dreads to hear

Outcast is all i get,
cause' of some things that i don't want to forget,
Can all this be changed?
In every four part song

People die cause of starvation,
People die of gluttony,
People would do anything,
Just to stop the four part song,

Blood drops is all i see,
Sorrows brought me to my knees,
No one is here for me,
Except for this four part song

I laid at my death bed,
My head filled with regret,
Why didn't i do a good deed,
As God did it for me
He put a song in my heart,
A four part song he put,
To lead more people to him
