Gradated Grey

My car radio's playing a song 
That makes me feel very strange 
It's taken so long 
Through the gradation of the grey scale 
A landscape like I've never seen 
As far as my eyes can see 
Out on the road 
I've seen so many shades, shades of grey 
Now I'm back in the tunnel again 
Every minute, every second 
I can feel it getting closer 
Speeding ahead 
To where grey meets white
