Manics non-standard songwriting credits

[gabo86]

Hello everyone.
As we all know, the songwriting credits in the first three Manics albums (and part of EMG) are: James + Sean music, Richey + Nicky lyrics. Then, James + Sean music, Nicky lyrics. In the latest albums, anyway, they stopped separating music and lyrics, writing "music and lyrics by Manic Street Preachers".
My question is: can we write a list (I'll edit this first post accordingly) where we track down "non standard songwriting credits"?.

For example, I'm sure James wrote the lyrics for (at least):
Ocean Spray
Firefight
I Think I Found It
Anthem For A Lost Cause
The Next Jet To Leave Moscow;

Then, Nicky wrote the music for:
Dying Breeds
Your Love Alone Is Not Enough (chorus)
The Long Goodbye
Lady Lazarus
She Bathed Herself In A Bath Of Bleach (verses)
Marlon JD
William's Last Words
4 Lonely Roads
As Holy As The Soil
Divine Youth

About the Richey/Nicky lyrics, are there some that are for sure only by Nicky (I don't know any) or by Richey (most out of THB, but I don't know which ones)?
And, about the music writing, have we got any evidence of Sean writing a specific song? We all know that James writes most of the music, but sometimes Sean stated that he wrote a specific song (I seem to remember Welcome To The Dead Zone).

Thanks to everyone who can help us out!
