Lyric 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
