speed of sound - Coldplay

Look up, I look up at night, Planets are moving At the speed of light. Climb up, Up in the trees, Every chance That you get, Is a chance you seize. How long Am I gonna stand, With my head Stuck under the sand? I'll start Before I can stop, Before I see Things the right way up.
All that noise, And all that sound, All those places I got found. And birds go flying At the speed of sound, To show you How it all began. Birds came flying From the underground, If you could see it Then you'd understand?
Ideas That you'll never find, All the inventors Could never design. The buildings That you put up, Japan and China All lit up. The sign That I couldn't read, Or a light That I couldn't see, Some things You have to believe, But others are puzzles, Puzzling me.
All that noise, And all that sound, All those places I got found. And birds go flying At the speed of sound, To show you How it all began. Birds came flying From the underground, If you could see it Then you'd understand? Ah... when you see it Then you'll understand?
