Song writing credits only count if you contribute to the actual arrangement or body of the song.
Putting bass on a track which merely mirrors the riff written by someone else isn't writing a song apparently.
Nor is playing a guitar solo on a song which someone else wrote. You didn't "write the song" technically. **
But whatever. Not all bands follow this rule. U2 have split everything 25% since day one.
I'd have preferred to see Hetfield/Ulrich/Hammett/Trujillo on everything
Kirk didn't even get a writing credit on Lords of Summer.
** - p.s. that Disposable Heroes-esque guitar climb in the chorus of Moth Into Flame was written by James. So Kirk really did just come in and do solos by the looks of it.

Also it's funny seeing people call this album "ThreeLoad" and say stuff like " I didn't wait 8 years for another LOAD.
Guess i'll have to wait another 8 years for a heavy album.."
This album is heavy as shit. If you just want every song to be fast thrash - Slayer are available.
