i dont know if this is applicable but conor oberst (bright eyes) adds musical stuff to his lyrics:
"And I sing and sing of awful things
The pleasure that my sadness brings
As my fingers press onto the strings
In yet another clumsy chord
Haligh, haligh, an awful lie
This weight will now be satisfied
I'm gonna give you only one reply
I know not who I am"
Bright Eyes - Haligh, Haligh, A Lie, Haligh
"But all I have for the moment is a song to pass the time
A melody to keep me from worrying
Oh, some simple progression to keep my fingers busy
And some words that are sure to come back to me "
Bright Eyes - A Song to Pass the Time
is that in any way relevant?
