Landline, by Colonial Skyway

You are the last person alive, a disembodied consciousness wandering the countryside in absolute solitude. The places you visit are benign and innocent under what would be normal circumstances to you, but now, devoid of all life, they are ghostly and abnormal. A host of life turned into a shell engulfed by the natural results of death.

This is your soundtrack. This is what that world sounds like.
