Radiohead Climbing up the walls

I am the key to the lock in your house That keeps your toys in the basement And if you get too far inside You ll only see my reflection It s always best when the covers up I am the pick in the ice Do not cry out or hit the alarm You know we re friends till we die And either way you turn I ll be there Open up your skull I ll be there Climbing up the walls It s always best when the light is off It s always better on the outs
