Not that my lyrics above are anything to do with what the final thing would be. The song would be massive to document as many of the high profile WADs as I could, this includes Ganymede, which can rhyme with "Shit with Speed" ;)
Rap? God fucking no. I see what you mean though. Maybe they should go on an ABAB style rhyme rather than AABB. I did say I'm not the best lyricist, and will probably be better once there's an actual structure to them.
