• Perhaps he is referring to the mentality of very arrogant and haughty people who see the universe as centered around them, while the picking at the scab of the idea of why and suddenly seeing things may refer to understanding and seeing the nature of such a mindset firsthand. Hence, 'things arn't as pretty on the inside' could be a realization of the beast we carry that often is invisible. The beast being a disconnect from others.
• Don't think this track is about God, though it could be considered spiritual. Basically very eastern, wei wu, buddhist, advaita. This is essentially saying that you don't exist, only in a relative sense. Nothing outside of your conciousness exists. You create this world. This life and all you see is just an elaborate dream of your own doing. In fact you don't even need to believe in existence in order to live. Try it and see how much anxiety you loose, when you no longer care whether you exist or not. People make others up just to hurt themselves. Say this World is real and nobody laughs. Say it is a dream and everyone desperately tries to hold onto some glimmer of an objective reality which by its very essence assumes an observer and an observed.
• It is referring to freeing your mind from control of others by realizing where and how you see the world (from in your head).
• His song is about conquering drug addiction
• For those of you who don't seem to get it, THIS SONG IS ABOUT THE MOVIE FIGHT CLUB! IT IS BEING SUNG FROM THE NARRATORS PERSPECTIVE (edward norton) TO TYLER DURDEN (brad pitt)
• It is about conquering the whole "Yes I believe in God and if I don't I will burn in eternal flames?" The fear of god which has been drilled into so many of us - now he simply says, it turns out i'm alone and i always was - you were never really real to begin with. i just made you up to hurt myself. there is no you (GOD) there is only me.
• There exists - along with the surface meaning - a deep meaning: 'ultimately you can only fuck yourself up'.
• On "Only", Reznor speak-sings his way to each chorus, playfully talking about picking scabs and other sorts of self-castigating things. And, wow, what a ridiculous chorus: "There is no fucking you/ There is only me." It's like he's singing to himself in the mirror, either restaging the Buffalo Bill scene from Silence of the Lambs, or the Jena Malone/Susan Sarandon hairbrush bit from Stepmom.
• Mi opinión: me recuerda a un personaje de A Scanner Darkly, un maniático obsesionado con que su casa está infestada de insectos (de hecho, se rasca compulsivamente como Trent Reznor en el vídeo)... Hay días en que se roza la locura, uno se siente tan aturdido que no sabe si es real, si algo vale algo, y no se tiene fuerzas para ver las partes positivas. Tal vez ese "You" sea una voz en su mente, que lo aprisiona y reprime, y tal vez ese pequeño agujerito con postilla es una forma de reflejar que va notando sus errores, que está autodescubriéndose y no le gusta lo que ve. O tal vez es la marca de una jeringuilla... o del cable que lo une a Matrix...

Aunque no sepa a qué se refiere en concreto... me gusta.
